111 of 111 diveable wrecks.
Lost in 1910, not found again until 1970. The Crompton, a 2,810-ton steel four-masted barque and veteran of many Atlantic crossings, met her end on the unforgiving western cliffs at Dromgour Point on Valentia Island. All crew survived -- five men scrambled up the cliff at Filenagaragh to safety. Six decades later, divers rediscovered heavy plate steel remnants, a second anchor, rusting chains from the forward chain locker, spars, and plating scattered on the rocky seabed below the dramatic cliff face. The main anchor was recovered and is now a well-known local landmark, displayed on Des Lavelle's forecourt on Valentia Island. An atmospheric dive beneath towering cliff scenery, accessed by boat from Valentia. Depths at Dromgour Point range from 20 metres to beyond 50.
The F2 never fired a shot at Scapa Flow, but she sank there all the same — dragged under by a winter storm on 30 December 1946, more than a year after the war she was built to fight had ended. A Geleiteboot escort boat, she was one of ten experimental vessels fitted with temperamental high-pressure Brown-Boveri turbines that gave her 28 knots but a reputation for mechanical misery. Lengthened by four metres in 1938 and repurposed as a torpedo recovery vessel, she surrendered to the Royal Navy in 1945 and was towed north to Scapa. Her stern now sits upright in 16 to 18 metres, with the forward section listing on its side — a compact, navigable wreck linked by a 30-metre line to the salvage barge YC21 that sank nearby in 1968 while attempting to scrap her. A 20mm gun from the F2 ended up on the barge, a small absurdity that divers can verify for themselves. At barely 18 metres, she is an ideal second dive or warm-up before the deeper German fleet wrecks.
One man survived -- blown clear into the sea by the force of the explosion. When a mine from UC-42 detonated amidships on 12 July 1917, the 37-metre armed minesweeper George Milburn was ripped apart while escorting the oiler SS Wylie from Queenstown to Milford. Eleven of the twelve crew died instantly. The sole survivor was picked up by a passing fishing boat. The wreck lies in two pieces at 23 metres west of Hook Head in Waterford Harbour. Local sub-aqua clubs leave a permanent shot line on the site, making it easy to locate. The relatively shallow depth allows extended bottom time, and DUSAC describe it as a rewarding afternoon dive. About 30 minutes by boat from Dunmore East. Designated war grave.
Swim inside the upside-down wheelhouse and look up: the crew's toilet and sink are stuck to what is now the ceiling. The Girl Arleen was a fishing trawler lost in a fog collision in 1995, now lying at 27 metres due east of Baggabaun Head off Hook Head. Mostly broken up, but the inverted wheelhouse is intact and absolutely teeming with marine life -- anemones, crustaceans, and fish have colonised every surface. Strong surface currents are typical but conditions are usually slack on the bottom. Considered one of the best summer boat dives in the Hook Head area, the Girl Arleen is accessible from Slade Harbour (4 miles) or Kilmore Quay. A surreal, memorable dive that rewards those willing to get inside the wreck.
When divers recovered the six-pounder Hotchkiss gun in 1990, they found a live round still in the breech. The restored gun now sits in the National Maritime Museum in Dun Laoghaire, but the Guide Me II herself remains upright and very intact at 32-38 metres on coarse sand, 1.5 kilometres southeast of the Muglins east of Dalkey Island. Built as an Aberdeen fishing boat in 1907, she was hired by the Admiralty in 1915 and fitted with the gun for anti-submarine patrol. A collision on 29 August 1918 sent her to the bottom, taking one crewman. Rediscovered in 1990 by diver Ivan Tunstead, the collision hole is clearly visible on the port side. At 26 metres long, a complete circuit is possible within no-decompression limits. Always a dark dive -- bring a good torch. Lobsters and conger eels throughout.
For the entire duration of World War I, the British Admiralty pretended HMS Audacious still existed. The King George V-class dreadnought battleship struck a German mine off Tory Island on 27 October 1914 -- one of the first major warship losses of the war. Despite hours of rescue attempts, she capsized after a magazine explosion. All crew were rescued by the White Star liner RMS Olympic, sister ship of the Titanic. The loss was kept secret to deny Germany a propaganda victory. The wreck now lies inverted at 58-68 metres depth, roughly 18 nautical miles northeast of Tory Island. Reaching it requires a three-hour-plus boat transfer and trimix capability, but the clear Atlantic water off Donegal often delivers visibility exceeding 15 metres. One of the most impressive technical dives in Irish waters.
There is truly nothing else like HMS M2 anywhere in the world. Originally completed in 1919 as a submarine monitor carrying a massive 12-inch gun, she was converted in 1927 into the world's first undersea aircraft carrier, fitted with a watertight hangar and catapult for a tiny Parnall Peto floatplane. On 26 January 1932, during a routine exercise off Portland, water flooded through the hangar and she went down with all 60 hands. The salvage investigation found those hangar doors standing open — a haunting detail that has fuelled debate ever since. She rests upright and intact at around 33 metres in Lyme Bay, her 90-metre hull still unmistakably that of a submarine, the cylindrical hangar forward of the conning tower instantly recognisable. As a designated war grave she demands the utmost respect, but for those qualified to make the dive, she offers a genuinely unique encounter with a one-of-a-kind vessel.
On 5 September 1914, just weeks into the First World War, HMS Pathfinder made unwanted history as the first major warship ever sunk by a locomotive torpedo fired from a submarine. SM U-21, commanded by Otto Hersing, struck the scout cruiser's forward magazine, and the resulting explosion tore the bow clean off. Of her complement, 259 men were lost. She now rests upright in around 60 metres of water off St Abbs, her hull intact from stern to bridge area but the bow section scattered where the magazine detonated. A designated war grave under the Military Remains Act, she may be visited but not disturbed. The dive is strictly technical territory — deep, cold and demanding — but carries a historical gravity that few wrecks anywhere in the world can equal. Those who descend to her pay their respects to a moment that changed naval warfare forever.
When HMS Scylla was scuttled in Whitsand Bay on 27 March 2004, she became Europe's first purpose-built artificial diving reef — and an instant Plymouth landmark. The last Royal Navy frigate built at Devonport Dockyard, she had served with distinction from 1970 until her 1993 decommissioning as the final Leander-class vessel on active duty. Cleaned of contaminants and prepared for her new role, she now sits upright on sand between 9 and 26 metres, her 113-metre hull colonised by a rapidly developing ecosystem of anemones, sponges and fish that marine biologists continue to study. Penetration has been off-limits since 2014 as the structure deteriorates, but the exterior swim-around remains a compelling dive: the bridge, gun mountings and flight deck are all recognisable. Paired with the James Eagan Layne just 540 metres away, she anchors one of southern England's most popular dive days.
A 17,000-ton ocean liner sitting upright on the seabed at 130 metres, largely intact, in water described as having awesome visibility. HMS Transylvania is among the deepest diveable wrecks in the region -- extreme technical expedition territory, accessible only to expert trimix or CCR divers. Built in 1925 by Fairfield Shipbuilding in Glasgow for the Anchor Line, she was requisitioned in August 1939 and converted to armed merchant cruiser F56, serving on the Northern Patrol. On 10 August 1940, U-56 torpedoed her approximately 40 nautical miles northwest of Malin Head. Taken in tow, she later foundered. Approximately 300 officers and ratings were rescued by nearby trawlers. The wreck requires a 3-4 hour boat transit from the Donegal coast.
Rammed by her own sister ship in fog, the 6,010-ton ironclad battleship sank with no loss of life -- and her captain never commanded a vessel again. On 1 September 1875, HMS Vanguard was en route from Dublin to Queenstown when HMS Iron Duke's underwater ram tore open her hull near the boilers. She went down in about 70 minutes. Rediscovered in 1985, the wreck is remarkably intact at 45-50 metres, tilted to starboard, rising approximately 16 metres from the seabed. The gun battery is the highest point. A spare iron propeller sits on deck. The layout can be deceptive -- divers report it is easy to unintentionally end up inside the hull. Protected under the National Monuments Act; a licence from the National Monuments Service is required. Fifteen miles southeast of Dun Laoghaire.
No distress signal. No survivors. No conclusive explanation. HMS Viknor vanished off Tory Island on 13 January 1915 with all 295 hands -- one of the worst Royal Navy losses off Ireland in World War I. Originally built as RMS Atrato in 1888, she was later sold and renamed The Viking for use as a cruise ship, then requisitioned by the Admiralty in late 1914 and sent to war. The cause of her loss was never determined, though the SMS Berlin minefield -- which also claimed HMS Audacious and SS Manchester Commerce -- is the prime suspect. The wreck was finally located in 2006 by the Irish survey vessel Celtic Explorer at 85 metres depth, 18 kilometres west of Tory Island. An extreme technical dive in exposed Atlantic conditions. Designated war grave.
The court-martial records have disappeared. The curse story has not. HMS Wasp was a Banterer-class gunboat ordered to assist in forcible evictions on Inishtrahull Island, north of Malin Head. According to Tory Island folklore, islanders "turned" a cursing stone against the ship. On 22 September 1884, running under sail with an inexperienced officer at the wheel and insufficient boiler pressure to manoeuvre, the Wasp ran onto rocks at the base of the Tory Island lighthouse, killing 50 of her 56 crew. The official verdict: navigational error. But the inquiry records have since vanished, and theories of sabotage persist. The wreck lies scattered in 8-18 metres near Tory Island -- an accessible but exposed Atlantic dive with over 140 years of intrigue.
Lying in just 12 metres of water off Bracklesham Bay, HMS A1 holds a unique place in British naval history: she was the very first submarine designed and built in this country for the Royal Navy. Constructed by Vickers in 1903, she had already survived one sinking — a collision with SS Berwick Castle in 1904 that killed eleven crew before she was raised — when she was repurposed as an unmanned torpedo target. In August 1911, operating on automatic pilot, she sank for good off Selsey Bill. Tidal currents slowly dragged her five miles along the seabed to her present position. The hull is virtually intact, with the bow standing proud while the stern disappears beneath a sandbank. Protected under the Protection of Wrecks Act since 1998, she requires a permit to dive, and the Nautical Archaeology Society has established a structured dive trail for visiting divers. For anyone interested in submarine heritage, there is no more historically significant shallow dive in British waters.
Six torpedoes from two separate U-boats over two days. That's what it took to sink the Justicia -- one of the largest vessels lost during World War I at 32,234 GRT and 237 metres long. Originally laid down as the Holland-America liner Statendam, she was completed as a British troopship. UB-64 torpedoed her northwest of Malin Head on 19 July 1918, but she stayed afloat and was taken in tow. The following day UB-124 found her and fired two more torpedoes. By noon she rolled over and sank. At 70 metres depth, over 25 nautical miles offshore, everything about the wreck is enormous: oversized chains, derricks, capstans on the foredeck, a massive anchor still in place on the broken-off bow. A three-hour-plus boat transfer is required. The sheer scale makes this one of the most extraordinary technical dives in the world.
"LIGHTHOUSE SERVICE" -- the words were painted in five-foot letters on both sides of the hull. It made no difference. On 19 December 1940, the Irish Lights tender ILV Isolda left Rosslare Harbour carrying crew and Christmas provisions for the Barrels and Coningbeg lightships. Three miles out, with the Saltee Islands off her starboard beam, a German Focke-Wulf Fw 200 Condor attacked without warning and sank her. Six crew members from Dun Laoghaire were killed. Ireland was neutral. The Isolda was on a humanitarian mission to supply lighthouses. She was 198 feet long, 734 tonnes, built at Dublin Dockyard and launched on 26 January 1928. The sinking remains one of the most poignant examples of the dangers faced by neutral Ireland during the Second World War.
In the sheltered waters of Killary Harbour -- Ireland's only fjord -- a supply vessel sits perfectly upright on sand at 27 metres, smothered in plumose anemones, dead man's fingers, and vivid orange, white, and yellow sponges. The Julia T spent decades serving the island communities of Inishturk and Inishbofin, delivering building materials until the 1980s, before sinking during a decommissioning tow. Now she is a paradise for underwater photographers: wrasse, spider crabs, squat lobsters, and scorpion spider crabs populate every surface. Featured by Scuba Diving Magazine as one of seven must-dive sites in Ireland. The fjord setting means she is diveable in almost all conditions, and penetration is possible. Boat dive from Scubadive West, Renvyle.
Beneath the sheltered waters of Bantry Bay lies one of the most archaeologically significant wrecks in Ireland -- a French frigate scuttled during the failed 1796-97 expedition to support Irish rebellion against British rule. La Surveillante went down on 2 January 1797 after her crew chose scuttling over capture by the Royal Navy. Lost for nearly two centuries, the wreck was identified in 1981 during marine surveys following the Whiddy Island oil terminal disaster, and confirmed in 1997 when the ship's bell was located. Preservation is exceptional: the wreck survives from the orlop deck down to the copper-sheathed keelson, with the entire site contained within just 50 by 25 metres. A nationally protected monument (NMS Wreck Number W08507), diving requires prior permission from authorities.
The Acclivity was a small but purposeful motor tanker, designed specifically for vegetable oil and wine cargoes, that met her end in the unglamorous fashion common to many working vessels — a fouled propeller, a failed tow, and a winter sea that would not forgive. Loaded with linseed oil, she limped south of the Farne Islands in January 1952 before the North Sea claimed her. Storms have since rolled her from her original upright position onto her port side, burying half the hull in sediment, but what remains visible is a riot of colour. At 29 metres she sits right at the recreational depth limit, offering a satisfying wreck dive without demanding decompression stops. Her compact 39-metre length means a single circuit is entirely achievable, and the various holes and openings invite closer inspection. Not the biggest or most famous wreck off Northumberland, but one that consistently delivers a good dive.
At 148 metres and nearly 11,000 GRT, the Aeolian Sky is one of the largest diveable wrecks off the Dorset coast — a modern freighter whose size dwarfs the elderly steamers that litter the surrounding seabed. She was barely a year old when fog and misfortune conspired against her in November 1979: a collision with the German coaster Anna Knueppell off Guernsey, a desperate attempt to reach Portland, and then the storm that finished her five miles south of St Aldhelm's Head. Lying on her port side between 18 and 30 metres, she offers a dive of genuine scale — four cavernous holds, imposing cargo derricks, and a stern superstructure that still reads as a functioning ship. Salvage charges reduced her height somewhat, but the intact sections retain an architectural quality that smaller wrecks simply cannot replicate. Moderate currents demand careful planning, but the reward is a dive that feels truly immersive.
Perched on the Gantocks rocks near Dunoon, the Akka consistently ranks among Scotland's top ten wreck dives — and she earns that reputation through sheer versatility. Her deck and superstructure sit between 16 and 24 metres, offering a satisfying dive for sport-qualified divers who want to explore companionways, holds and the wheelhouse area. More experienced divers can push deeper to the bow and stern sections at 30 to 40 metres for a different perspective. Built in wartime Gothenburg in 1942, this Swedish motor vessel was undone not by conflict but by a mundane steering failure in April 1956 that put her hard onto the rocks. The Firth of Clyde location means she is reachable from multiple launch points, and she provides a welcome alternative to the west-coast circuit centred on the Sound of Mull.
Her masts still break the surface. In the channel between Bere Island and the mainland at Castletownbere, the MV Bardini Reefer sits almost complete in just 15 metres of water -- masts protruding above the waterline, making the wreck impossible to miss. This 3,976 GRT Panamanian factory fishing vessel caught fire while at anchor in Bantry Bay and burned for three days before sinking on 15 December 1982. All crew were rescued by local boats. Gentle currents in the sheltered harbour have encouraged dense marine growth on the superstructure. Divers can explore the periphery and full length of the deck, viewing the boiler room, mast, and funnels. Penetration is possible through some openings. The site deserves at least two dives and is accessible to all levels including freedivers. Visibility varies between 3-5 metres.
Dublin was desperate for food. The winter of 1947 was the worst in living memory -- freezing conditions, snowstorms, snowdrifts for weeks. On 4 March, the Norwegian motor vessel Bolivar was making her way across the Irish Sea with badly needed grain and supplies from Uruguay when a blinding snowstorm struck and she ran onto the Kish Bank sandbank. Despite attempts to pull free, the ship broke in two. All crew were rescued. The engine room was salvaged and the wreck partially dispersed with explosives in 1948 as a navigation hazard. Today the remains lie in 4-10 metres, split into two sections about 150 metres apart. The shifting Kish Bank sands alternately expose and bury different parts. Best dived 1.5 to 2 hours before high or low water at Dublin Port.
When gale-force winds drove the Cita onto Newfoundland Point in March 1997, Scillonians found their beaches littered with everything from tobacco to computer parts, sparking a modern-day 'wrecking' sensation covered by national media. The ship herself split and settled into two distinct sections that now offer remarkably different dives. The bow section starts at just 8 metres and descends to 27, making it accessible to intermediates, while the stern drops away to 40 metres for those wanting more of a challenge. Both sections retain substantial steel structure with genuine penetration routes through cargo holds and passageways. What elevates the Cita above many UK wrecks is its setting: Scilly's Atlantic-washed waters routinely deliver 20-30 metre visibility, transforming what would be a torchlit crawl elsewhere into a wide-angle spectacle. Only three dive charters operate in the islands, so forward planning is essential.
At 294 metres long and 169,469 deadweight tonnes, the Kowloon Bridge wreck is one of the largest diveable shipwrecks on the planet. She was a Bridge-class OBO carrier that developed structural cracks in heavy Atlantic weather in November 1986 while carrying 160,000 tonnes of iron ore from Canada. Refused entry to several ports, she broke free from tugs and drifted onto the Stags rocks off Toe Head in West Cork. All 28 crew were helicoptered to safety. The wreckage now sprawls across a wide seabed area from 5 to 34 metres, offering diving for a range of experience levels. Iron ore pellets blanket the site. Marine life is prolific -- seals, large shoals of pollock, conger eels, and dense anemone growth thrive on the scattered hull sections, some of which rise more than 10 metres off the seabed.
Standing bolt upright on the seabed with her mast still rigged, the Lucy looks less like a wreck and more like a ship that simply forgot to come back up. This Dutch coaster met her end in dramatic fashion in 1967: her calcium carbide cargo began reacting with seawater after she struck Blackstones Reef, threatening an explosion that forced the crew to abandon ship. The rising tide then prised her free and the current carried her to her final resting place north of Skomer Island. Within the Skomer Marine Nature Reserve, the wreck has become a living reef — plumose anemones, dead man's fingers, and nudibranchs carpet every surface, while the dark interior rewards those brave enough to bring a torch inside. The strong tides that guard Jack Sound demand careful slack-water timing, but divers who get the window right encounter one of the most photogenic intact wrecks anywhere in Wales.
Hollywood came calling for this wreck. The MV Ranga, a 1,586-tonne container ship, was driven onto the rocks at Dunmore Head near Coumeenole Beach on the Dingle Peninsula on 11 March 1982 after losing power in a severe storm -- on her maiden voyage under her new name. All fifteen crew were rescued, some by breeches buoy rigged by Dingle Fire Brigade, the rest by RAF helicopter. Captain Miguel Angel Diaz Madariaga was the last to leave. The ship split in two. In 1991, the stern section with superstructure was hauled away for the filming of Far and Away starring Tom Cruise. What remains lies in shallow water from 2-12 metres, accessible but subject to surge and wave action. The dramatic Slea Head scenery makes the setting as memorable as the dive.
From smuggling ship to artificial reef. Seized by the Irish Revenue Commissioners in 2014 while carrying 32 million cigarettes and 4.5 tonnes of tobacco -- a haul worth EUR 14 million in lost tax revenue -- the MV Shingle was deliberately sunk on 18 September 2024 in Killala Bay to create Ireland's first purpose-built artificial reef. All asbestos and pollutants were stripped from the 60-metre, 42-year-old hull before the controlled sinking. Then Storm Eowyn arrived on 24 January 2025 and broke the wreck into three sections -- bow, stern, and midships -- now lying 25-200 metres apart. Rather than a disaster, this created three distinct dive sites rather than one, with rapid barnacle growth and fish colonisation already established across all sections. Sits at approximately 29 metres. A cooperative venture between Killala Bay Ships 2 Reef, Revenue Commissioners, and Mayo and Sligo County Councils.
Reaching the Tapti takes commitment — a 35-nautical-mile boat ride from Lochaline through some of Scotland's most scenic coastal waters — but those who make the journey find a wreck that rewards the effort handsomely. Built on the Clyde in 1945, this cargo motor vessel met her end in January 1953 when a storm drove her onto the rocks of Gunna Sound between Coll and Tiree. She broke into four distinct sections, and today the bow piece is the star of the show, lying on its port side and towering 15 metres off the seabed. Devonshire cup corals, soft corals and plumose anemones smother every surface, while the boiler, mast and winches remain clearly identifiable. The site is exposed and weather-dependent, giving it an adventurous quality that the more sheltered Mull wrecks lack.
She struck Howth Head once. Backed off. Then struck again beneath the Baily Lighthouse and sank in fifteen minutes. On the night of 14 February 1853, the paddle steamer PS Queen Victoria -- built in 1838 for the City of Dublin Steam Packet Company's Dublin-Liverpool mail route -- departed Liverpool with approximately 100 passengers into a snowstorm. Around 02:00 on the 15th she hit the headland. Captain Jones tried to make harbour, but the damage was catastrophic. Dead in the water and filling fast, the ship drifted and struck a second time. Around 83 people perished including the captain. One lifeboat, carrying 17 survivors, reached shore. The Board of Trade blamed the captain, first officer, and lighthouse crew. The wreck lies at approximately 18-20 metres south of the Baily Lighthouse. Permit required to dive.
The disaster was raised in the House of Commons. On 28 January 1894, the three-masted iron-clad barque Port Yarrock -- carrying refined copper ore worth GBP 100,000 from the US to Cobh -- was driven onto Kilcummin strand in Brandon Bay after dragging her anchors for over a week in a disabled state. All 20 British and Scandinavian crew perished; seven bodies were never recovered. The Court of Inquiry blamed the managing owner, Robert John Rowat, for allowing the ship to sail short-handed and for failing to send instructions to move her to safety. The wreck is largely buried in sand with the bowsprit visible at extreme low spring tides. An anchor and centenary memorial stone placed in 1994 stand on shore above Kilcummin strand. Very shallow shore exploration in the Maharees area.
The largest wreck on the entire Sussex coast, the RMS Alaunia was a Cunard Line ocean liner of over 13,000 tons — a ship built for the transatlantic run that could carry more than 2,000 passengers in an age when crossing by sea was the only option. In 1914 she made history as the first Cunard vessel to transport Canadian troops to the war in Europe. Two years later, outbound from London to New York on 19 October 1916, she struck a mine off the Royal Sovereign Lightship and went down with the loss of two crew. She now lies on her port side in around 36 metres off Eastbourne, her 159-metre hull standing 10 metres proud of the seabed in places. The bow cants at a dramatic 45-degree angle with the port anchor still hanging in its hawsehole, and rows of portholes remain in situ along the hull plating. It is a dive of genuine scale — a cathedral of riveted steel in the grey-green Channel water.
When she launched in 1901, the RMS Celtic was the biggest ship in the world -- the first vessel in history to exceed 20,000 gross tons, surpassing even the legendary SS Great Eastern. Built by Harland and Wolff in Belfast for the White Star Line as the first of their Big Four quartet, she measured over 700 feet and 20,904 GRT. Her end came ignominiously on 10 December 1928, blown onto rocks at Roches Point while waiting for a harbour pilot at Cobh. Stuck on Cow-and-Calf Rock, wave action caused such structural damage that she was declared a total loss within a week. Sold to Danish firm Petersen and Albeck, she was broken up in situ by 1933. Tragedy struck again in November 1929 when hydrogen sulphide gas from rotting cargo killed four salvage workers. Artifacts found their way into Cork homes. The sparse remaining wreckage at 10-20 metres requires local knowledge to locate.
Over 564 dead -- the greatest single loss of life in the Irish Sea, and one of the most devastating maritime disasters of World War I. On 10 October 1918, UB-123 fired three torpedoes at the RMS Leinster near the Kish Bank. The first missed. The second struck the port side. As Captain Birch tried to turn back toward Kingstown, the third torpedo cut the ship almost in half. Twenty-one of 22 postal sorters aboard perished. The City of Dublin Steam Packet Company mail steamer, built in 1896 at Birkenhead, now lies at 28 metres approximately 4 nautical miles east of the Kish Light. The bow stands proud of the seabed; the rest is largely collapsed into sand. The anchor, recovered in 1991, is displayed at Carlisle Pier, Dun Laoghaire. Strong currents and poor visibility make this an advanced dive. War grave.
Eighteen minutes. That's all it took for the Lusitania to disappear beneath the Celtic Sea on 7 May 1915, taking 1,198 souls with her. A single torpedo from U-20, fired eleven miles south of the Old Head of Kinsale, struck the starboard side -- followed by a mysterious second explosion whose cause is still debated. The sinking turned American opinion against Germany and altered the course of World War I. Today the wreck lies on her starboard side at approximately 93 metres, heavily collapsed and continuing to degrade from corrosion and tidal currents. Diving the Lusitania demands advanced trimix certification, deep wreck experience, and permission from Irish authorities. Visibility typically runs 5-8 metres in moderate to strong currents. This is a protected site under Irish law, and the Irish Examiner reported in 2024 that efforts are underway to document and recover artefacts before further collapse.
Her iron hull made the compasses lie. The RMS Tayleur, the largest iron clipper of her kind when built in 1853, departed Liverpool for Melbourne on her maiden voyage with over 650 souls aboard. Within 48 hours, fog and storm engulfed the ship. The crew believed they were sailing south through the Irish Sea -- they were actually heading west, straight for Lambay Island. An undersized rudder and improperly stretched rigging sealed her fate. She struck the rocks on 21 January 1854, killing over 370 people. The wreck at 9-17 metres in Tayleur Bay includes hull plates, a donkey engine, the lower mast, crockery, roof tiles, and even tombstones from the cargo. PROTECTED WRECK -- it is illegal to dive without prior permission from the Office of Public Works.
Perfect for your first wreck dive. The Rath Connla, a fishing trawler that sank at moorings in 2007, sits intact at just 16 metres in the calm, current-free waters of Killary Harbour. A mooring buoy attached to her bow makes the wreck easy to find. Anemones, scallops, tube worms, and whelks have colonised every surface -- a microcosm of the rich invertebrate life found throughout Ireland's only fjord. Shore-accessible from Rosroe Pier, about 200 metres northeast, this is an ideal training wreck for newly qualified divers. The sheltered setting provides minimal current and calm conditions year-round. Combine with a boat dive on the nearby Julia T for a rewarding full day of diving. Scubadive West in Renvyle is the local operator.
Visibility can exceed 40 metres here -- some of the clearest water on the planet, thanks to the rock and shale seabed off the Donegal coast. SM U-89 sits at approximately 62 metres depth, 25 miles off Malin Head, remarkably well preserved with deck guns at both bow and stern and torpedoes still in storage. She surfaced just 200 yards ahead of the cruiser HMS Roxburgh on 12 February 1918. The cruiser rammed the conning tower without hesitation, sending U-89 to the bottom with all 43 crew. Large cod, pollock, and conger eels patrol the wreck. Diving is from specialist charter boats out of Malin Head using trimix, with bottom times of around 30 minutes and total run times of 85 minutes. Designated war grave.
On 28 October 1918, with the Armistice barely a fortnight away, UB-116 attempted one of the war's most audacious submarine operations: a solo penetration of Scapa Flow through the mined entrance at Hoxa Sound to attack the British Grand Fleet at anchor. She never made it. British hydrophone operators tracked her approach and detonated a remote-controlled mine that killed all 34 crew — the last U-boat lost in the First World War. Raised in 1919, she broke free and sank again at the mouth of Pan Hope Bay; a controlled explosion later dealt with her remaining live torpedoes, and the blast left her barely recognisable as a submarine. What remains is a scattered field of torn steel and bent piping in 26 to 32 metres, with the conning tower standing as the only clearly identifiable feature. Orientation is challenging, but the story gives every twisted plate its weight. This is the physical full stop at the end of the U-boat war.
The crew of UC-42 were laying mines to destroy other ships when one of their own mines destroyed them. On 10 September 1917, this German UC II-class minelaying submarine was deploying a minefield at the entrance to Cork Harbour off Roches Point when a mine detonated, killing all 27 crew instantly. The wreck was relocated by divers in 2010 in approximately 28-30 metres and subsequently designated a war grave under the National Monuments Acts. She rests on her port side with the keel visible and an external bow torpedo tube lying in the silt beneath. In 2024, divers from Blackwater Sub Aqua Club and Mizen Archaeology recovered one of the propellers after months of careful excavation -- a significant maritime heritage event covered by RTE and the Irish Examiner. A licence under the National Monuments Acts is required to dive this protected site.
Brummer earned her name — "Growler" in German — in October 1917, when she and her sister Bremse ambushed a British convoy bound for Norway and left two destroyers and nine merchant ships on the seabed in a single action. A century on, she lies on her starboard side in Gutter Sound, one of the few German warships that salvage teams never touched. That neglect is the diver's gain. The brass bridge, gleaming dully in torch light, has become one of the defining images of Scapa Flow diving. Mine rails run along the deck where 400 contact mines once sat ready for deployment, and scattered arsenal pieces litter the seabed around the hull. At 22 to 36 metres, the Brummer sits in a comfortable depth band for advanced sport divers and rewards repeat visits — every pass along the hull seems to reveal another fitting the salvage crews left untouched.
Last of the line. The Coln was the lead ship of the final class of light cruisers the Imperial German Navy would ever build, and she arrived too late to fire a shot in anger. Today she is the most intact of the four cruisers left in Scapa Flow, lying on her starboard side with many prominent deck features still in place. At 155 metres long and capable of 27.5 knots, these were serious fighting ships — eight 15cm guns, torpedo tubes, mine rails for 200 contact mines, and a complement of 559 men. The wreck rewards a methodical circuit: starboard side in 34-36 metres, with the top of the hull at a manageable 22. Navigation is straightforward, making the Coln the cruiser most often recommended to divers stepping up from blockship depths for the first time. The reward is a warship that still looks like a warship, every rivet and fitting a monument to the industrial ambition of a navy that briefly challenged British supremacy at sea.
Most divers meet the Dresden on their first morning in Orkney. She has become the traditional opening dive of a Scapa week, and for good reason: the bow rests at 23 metres, shallow enough for a conservative shakedown after a long journey north, while the stern drops away to 38, deep enough to stretch the legs later in the trip. That versatility is no accident of geography — the Dresden lies on her port side along a natural gradient, the hull itself mapping out a progression from comfortable to challenging. Sister ship to the Coln and one of the last light cruisers the Kaiser's yards would ever launch, she carried eight 15cm guns, torpedo tubes, and rails for 200 mines at close to 28 knots. The wreck retains intact sections along much of its length, and the depth profile means a single dive can encompass both a leisurely survey of the shallows and a purposeful push into the darker water beyond.
At just 16 to 27 metres, the Karlsruhe is the shallowest of the seven German fleet wrecks and the one that gives most generously with bottom time. Forty minutes on a single dive is routine rather than exceptional here — long enough to properly explore a 151-metre light cruiser rather than merely visit one. She sits at about 45 degrees, starboard side down, hull and fittings remarkably well preserved for a ship that has spent more than a century underwater in Orkney tidal waters. The Karlsruhe belonged to the Konigsberg class of 1915, with 60mm belt armour, eight 15cm guns, torpedo tubes, and mine rails: a ship designed to sprint at 27.5 knots, lay death in the water, and fight her way home. For divers building confidence before tackling the deeper battleships, she offers an unhurried introduction to the scale and craftsmanship of the Kaiser's fleet.
Ravaged by decades of industrial salvage, the Konig offers something none of the other Scapa battleships can: a cross-section through the guts of a WWI dreadnought. Where Metal Industries tore away hull plating and superstructure in the 1960s, the armoured citadel now stands exposed — twelve inches of dovetail-jointed steel that once protected the magazines. Seven casemate guns lie upside down on the seabed along the starboard side like fallen dominoes. The wreck is the least-dived of the three battleships, partly because pre-dive route planning is essential amid the tangled debris field of wires, blocks, and davits. That quietness is its own reward: schools of pollock patrol the wreckage undisturbed, and a careful diver can spend an entire dive tracing the skeleton of a ship that traded broadsides at Jutland.
Where other Scapa battleships demand technical qualifications, the Kronprinz Wilhelm meets experienced sport divers on their own terms. Her tilted posture — port side uppermost, starboard buried in the seabed — places the shallowest hull plating at just twelve metres and stretches the dive profile all the way down to 43 at the deepest point. The real draw is the main armament: half of the original complement of 12-inch guns remain visible and reachable, turret after turret lined up along a hull that still measures 146 metres on the seabed. It is the closest most recreational divers will ever come to comprehending the firepower of a dreadnought. Diveable at any state of tide and usually marked with two small buoys, the Kronprinz is the most forgiving of the three battleships — and arguably the most spectacular for the qualification required.
Often called the jewel of Scapa Flow, the Markgraf is the deepest and best-preserved of the three battleships still resting on the seabed. At 47 metres her keel breaks the surface of diver ambition — this is not a dive you stumble into, but one you train for. The reward is a warship that still looks like a warship: intact bow, stern, and rudders convey the sheer scale of a 175-metre dreadnought that once carried over a thousand men into the maelstrom at Jutland. Because the superstructure caught on the seabed before she could roll fully, much of the underside architecture remains visible rather than crushed. Visibility can swing from five to fifteen metres with the tide, so timing matters. For divers qualified at extended range, the Markgraf is the definitive Scapa experience — a cathedral of riveted steel suspended in the cold, green half-light of Gutter Sound.
At 7,717 tons, the Hamburg America Line's Abessinia holds the distinction of being the largest ship ever wrecked on the Farne Islands — a title that gives some idea of the scale of wreckage awaiting divers on the Knivestone reef. She ran onto the rocks in September 1921 on her way home from Chile, and the reef has been digesting her ever since. Her boiler stands clear of the surrounding jumble at 18 metres as the main reference point, while the bow section — complete with anchor and chain — has slid down to the western side of the reef. Gullies criss-crossing the rock are stuffed with additional wreckage that rewards careful exploration. What makes Knivestone special is the wildlife: the Farne Islands' famous grey seals treat diving visitors as entertainment, spiralling around you mid-dive with unnerving confidence. The rocks only show at low-water springs, so the reef's location is a navigational challenge in itself.
Survivors were lowered down a 45-metre cliff face. When the SS Alondra ran aground on Kedge Rock off Baltimore in dense fog on 29 December 1916, sixteen of her 40 crew drowned taking to a ship's boat. The Baltimore lifeboat launched twice but couldn't reach the vessel. At daylight, rescuers arrived with rocket apparatus and two Royal Navy trawlers. Together they saved 23 men -- Archdeacon Becher and Lieutenant Sanderson each received the RNLI Silver Medal for Gallantry. Built in 1899 for the Rio Tinto Company, the 2,500 GRT steel steamship now offers multiple depth zones from 6 metres (forecastle with anchor winches) down to 46 metres (stern section), with prominent boilers at 20 metres surrounded by hull plating that houses large conger eels. A popular Baltimore dive; strong tides dictate slack water timing.
One of six ships lost. The City of Cork Steam Packet Company was systematically gutted by U-boat warfare during World War I, and the SS Ardmore was among the toll. Built in 1909 at the Caledon Shipbuilding & Engineering Co. in Dundee, 79.3 metres long with an 11-metre beam, she was torpedoed by SM U-95 on 13 November 1917 while carrying general cargo from London to Cork. The attack in St George's Channel, 13 nautical miles west-southwest of the Coningbeg Lightship, killed 19 of her 27 crew. The cumulative losses nearly bankrupted the company. After the war, they rebuilt -- replacing the Ardmore with the SS Ardmore II. The wreck lies in St George's Channel off the Wexford coast.
Captain Karl Spindler chose to scuttle his ship rather than let 20,000 rifles fall into British hands. The SS Aud -- actually the SS Libau, a German vessel disguised as a Norwegian steamer -- was carrying 20,000 rifles, a million rounds of ammunition, and ten machine guns for the planned 1916 Easter Rising. After sailing from Germany around Scotland, she arrived off the Kerry coast on 20 April 1916 but failed to connect with the Irish rebels due to miscommunication. Intercepted by the Royal Navy and escorted into Cork Harbour, Spindler ordered scuttling charges set. The Aud sank on 22 April with her entire weapons cargo. The wreck at approximately 30 metres in Cork Harbour is very broken up, but boilers and thousands of rifle bullets remain visible among the wreckage. One of the most historically significant wrecks in Ireland.
Friday the 13th lived up to its reputation. On 13 April 1917, the SS Bandon struck a mine from German submarine UC-44 off Mine Head while sailing from Liverpool to Cork. The blast beside the engine room killed 28 crew; only 4 survived, including Captain Kelly. In a grim twist, UC-44 herself was destroyed just four months later by one of her own mines off Dunmore East, with her commander Kurt Tebbenjohanns as the sole survivor. The Bandon wreck lies badly broken up at 33-34 metres, oriented east-west. INFOMAR multibeam surveyed. More challenging than nearby SS Folia -- heavier bottom current and poorer visibility demand precise slack-water timing. Built in 1910 by Swan Hunter, Newcastle-upon-Tyne, 81.1 metres long. Boat dive from Dungarvan. War grave.
If any single wreck can claim to have introduced Scotland to recreational diving, it is the Breda. Bombed by a Luftwaffe Heinkel in the Firth of Lorn in December 1940, this Dutch cargo steamer was beached in Ardmucknish Bay — only for winter gales to drag her back into deeper water where she settled upright on the seabed. Her sheltered position just minutes from Oban harbour makes her accessible when more exposed sites are blown out, and the absence of strong tides means conditions are forgiving for newer divers working toward their first proper wreck penetration. The superstructure sits between 11 and 19 metres, with the seabed at around 30. Marine growth is lush, with dahlia anemones, soft corals and shoals of pollack patrolling the companionways. Thousands of divers visit her each year, yet she never feels crowded underwater.
Twenty miles out from the Pembrokeshire coast, the Smalls lighthouse marks one of the most treacherous reefs in the Irish Sea — and the Cambro is its best-known casualty. This steel steamer, loaded with Spanish pyrites, was swallowed by fog in May 1913 and drove straight onto the rocks barely 150 metres from the lighthouse. The wreck itself is largely broken apart, though the stern section and boilers retain enough shape to anchor a dive. But the Cambro's real claim to fame came decades after her loss: in 1991 a sports diver found a Viking sword hilt guard decorated with silver wire and niello among the wreckage, a stunning artefact from centuries before the steamer existed, presumably washed onto the reef from an older, unknown wreck. Getting to the Smalls requires a dedicated long-range boat trip and a cooperative weather window, so each visit carries the earned satisfaction of a genuine offshore expedition.
Bound for Montreal with capacity for 596 passengers and a crew of 57, the SS Carthaginian never made it past Malin Head. On 14 June 1917, this 4,444 GRT Allan Line steel steamship struck a mine laid by German submarine U-79 approximately 2.5 miles northwest of Inishtrahull Lighthouse. Built in 1884 by the Govan Shipbuilding Co. for the Glasgow-Montreal route, she measured 116 metres long and 21 metres wide. The wreck sits at approximately 58 metres with a maximum height of 4.3 metres above the seabed -- a relatively flat profile at depth. Part of the extraordinary concentration of wrecks off Malin Head that makes this stretch of the Donegal coast one of the premier technical dive destinations in the world.
Torpedoed, then shelled 20 times by the surfaced U-boat for good measure. The SS Castle Eden, a 1,949 GRT steam collier fitted with a 13-pounder stern gun, departed Glasgow at 3:30am on 4 March 1918 carrying 2,900 tons of coal and timber for the Royal Navy at Lough Swilly. SM UB-110 torpedoed her engine room, then surfaced and pummelled the stricken ship with 20 shells. Remarkably, all crew survived. The wreck at 31-32 metres in Culdaff Bay off Malin Head is broken to seabed level by Atlantic groundswell, but rewards patient exploration. Divers find a dense shoal of pouting at the boilers, conger eels in gaps in the plating, the triple-expansion engine fallen to starboard, greenhouse-like ventilation hatches, and a large steering quadrant at the stern. INFOMAR has produced a 3D model. Featured in Divernet Wreck Tour No. 111.
Longstone lighthouse — made famous by Grace Darling's 1838 rescue — watches over one of the Farne Islands' most dramatic underwater landscapes, and the Chris Christensen occupies pride of place at its base. This Danish steamer, running light from Aarhus to pick up cargo at Newcastle, misjudged the reef in February 1915 and came to grief on its south-eastern tip. Her remains have cascaded down an underwater cliff: the boiler and triple-expansion engine sit at around 30 metres, with wreckage tumbling over boulders down to 40. The depth and currents make this a dive for experienced visitors only, but the reward is a site with genuine vertical drama — something rare in the generally flat seabed of north-east England. The nearby SS Coryton wreck adds a bonus target for those with gas and time to spare on the same descent.
Dense fog and the towering cliffs of the Old Head of Kinsale proved a fatal combination. On 22 June 1892, the Inman Line passenger liner SS City of Chicago -- 132 metres long and approximately 5,200 GRT, built by Charles Connell & Co. in Glasgow -- ran aground at Ringagurteen Point while on passage from New York to Queenstown and Liverpool. All passengers were rescued safely with their baggage, but twelve crew drowned when a rescue boat was swamped. For three days the ship held together against relentless Atlantic pounding before listing and breaking apart. The wreck now lies at approximately 20 metres at the foot of the dramatic Old Head cliffs, offering an accessible and scenic dive near one of Ireland's most famous headlands -- and not far from the resting place of the Lusitania.
Two ships. One U-boat. Two days. Eighty-three dead -- sixty-seven of them from a city of just 28,000 people. On 15 December 1917, U-62 torpedoed the SS Formby on the Liverpool to Waterford route. Bad weather delayed the news. Two days later, the SS Coningbeg sailed the same route, unaware her sister ship lay on the bottom. U-62 was still there. All 44 aboard the Coningbeg perished. Originally built as SS Clodagh by Ailsa Shipbuilders in Troon in 1903, the Coningbeg was a Clyde Shipping Company cargo vessel serving the Waterford trade. The dive site off the Wexford coast features strong currents but prolific fish life and colourful marine growth. Together with the Formby, this twin tragedy remains one of the worst maritime disasters of WWI off the Irish coast.
Two torpedoes, five minutes, twelve dead. SM U-103 struck the SS Cork on 26 February 1917 while she crossed the Irish Sea from Dublin to Liverpool carrying sheep, horses, and cattle. The first torpedo hit the engine room; the second struck near the foremast, destroying a lifeboat and eliminating any margin for escape. Built for the City of Dublin Steam Packet Company for the cross-channel trade, the Cork disappeared beneath the waves barely five minutes after impact, nine nautical miles northeast of Point Lynas, Anglesey. Seven passengers and five crew were lost. The wreck now lies upright and largely intact at 48 metres depth in the Irish Sea -- a well-preserved snapshot of early 20th-century cross-channel commerce.
The Dakotian's end came with shocking speed. A Heinkel 111H bomber dropped a parachute magnetic mine into Milford Haven in November 1940, and when it detonated against the anchored cargo steamer she went down in barely three minutes — one of the earliest parachute mine casualties in Welsh waters. At 6,426 tons she was a substantial vessel, and even lying on her side she retains enough structure to fill a dive. The depth range of 7 to 19 metres puts her within reach of intermediate divers, though the visibility in this part of Milford Haven can be challenging and the tides demand respect. What the site lacks in crystal water it makes up for in atmosphere: swimming along a 120-metre hull canted on its beam ends, knowing how suddenly and violently her war ended, gives the Dakotian a sombre character that clear-water wrecks sometimes lack.
Grassholm is best known for its 36,000 pairs of nesting gannets — the third-largest colony in the world — but beneath the waves on the island's south-eastern flank lies the Dalserf, a Cardiff coal carrier that struck the rocks in July 1910. All 27 crew survived, though the ship did not. Salvors stripped her of non-ferrous metals long ago, but the triple-expansion engine with its distinctive three-cylinder arrangement and the boiler still mark the centre of the site at around 20 metres. The real draw is the setting: diving among boulders beneath a volcanic island ten miles offshore, with gannets plunge-diving into the water around your boat, is an experience that no shore dive can match. Like the Smalls, reaching Grassholm requires settled conditions and a skipper who knows the reef, so each successful dive here feels properly earned.
Sherman tanks sit upright on the seabed at 67 metres, some perfectly intact, others still racked neatly in the holds three deep. The SS Empire Heritage was a 15,702 GRT tanker carrying aviation fuel, tanks, and half-track military vehicles from New York as part of Convoy HX-305 when U-482 torpedoed her on 8 September 1944 approximately 20 nautical miles northwest of Malin Head. She went down in under five minutes, killing 113. Thirty minutes later, the same U-boat torpedoed the rescue vessel Pinto as she picked up survivors. The sight of WWII military vehicles entangled with the wreckage is unique among Irish dive sites. Clear Atlantic water off Donegal often provides visibility exceeding 15 metres. The wreck is a designated war grave.
"Possibly the best wreck dive in Ireland." That is the verdict of local charter operators on the SS Folia, and the numbers back it up: relatively light currents and an average bottom visibility of 9 metres or more -- exceptional for Irish waters. This former Cunard liner of 6,705 GRT was torpedoed by U-53 under the highly decorated Hans Rose on 11 March 1917, 4 nautical miles off Ram Head, Ardmore. The third officer spotted a periscope 150 metres away, then two torpedo wakes. U-53 surfaced, circled, shelled the ship four times, and fired a second torpedo. Seven crew died. Badly broken up at 33-38 metres, but bow, boilers, stern with rudder, and an anti-aircraft gun remain as high points. Spent artillery shells from her 4,400-tonne cargo litter the seabed. Takes several dives to appreciate fully. Licence required from National Monuments Service. Boat from Dungarvan.
Nobody in Waterford knew. Bad weather had cut the telegraph, and it was assumed the Formby had simply sheltered from the storm. In reality, U-62 had torpedoed the Clyde Shipping Company cargo vessel on 15 December 1917 while she carried cattle from Waterford to Liverpool, killing all 35 crew. Two days later, her sister ship SS Coningbeg sailed the same route into the same waiting U-boat. All 44 aboard the Coningbeg died too. Of the 83 killed across both sinkings, 67 were from Waterford and surrounding communities including Faithlegg and Cheekpoint. The double tragedy devastated the waterfront community and is commemorated as one of the worst maritime disasters of World War I off the Irish coast.
The Gascony presents a puzzle that rewards patient exploration. Attacked by UC-75 on 18 January 1918, this armed cargo steamer broke in two and sank the following afternoon near Selsey Bill, coming to rest upside down on the edge of the Owers — a notorious shallow bank that has claimed countless vessels over the centuries. Her inverted orientation makes navigation tricky: what should be the deck is buried, and you swim beneath the keel looking up at the hull plating. Among the scattered cargo, the wheels of army gun carriages poke through the wreckage, a reminder that she was doing war work when the torpedo found her. At 27 to 30 metres she sits in nitrox-friendly territory, though currents near the Owers demand timing. For experienced sport divers who enjoy reading a wreck's story from its remains rather than its silhouette, the Gascony delivers a satisfyingly cerebral dive.
St Abbs is one of Scotland's great dive destinations, and the Glanmire is its signature wreck. First explored by divers in 1965, this iron steamer has been introducing east-coast divers to wreck diving for over sixty years. She hit Black Carr Rocks in thick fog on a summer's day in 1912, carrying general cargo from Amsterdam to the Forth ports, and everyone on board survived. Now lying broken between 20 and 35 metres with her bow facing the coast, she sits within the St Abbs Voluntary Marine Reserve — an area renowned for its clear water and prolific marine life. Visibility here regularly exceeds what divers encounter on Scotland's west coast, and the wreck is carpeted in soft corals, anemones and encrusting sponges. A few hundred metres offshore and well within boat range, she is the perfect gateway to the exceptional diving this stretch of Berwickshire coastline has to offer.
Lethegus Rocks south of St Agnes claimed two cargo steamers eleven years apart, and the result is one of the most unusual dive sites in British waters. The German Hathor, dragged helplessly from her tow across the Atlantic in 1920, came to rest directly on top of the British Plympton, wrecked in fog back in 1909. The tangled marriage of the two hulls creates a complex underwater landscape where it is genuinely difficult to tell where one vessel ends and the other begins. The Hathor's triple-expansion engines and twin boilers provide the main orientation points, clearing at around 25 metres with the seabed falling away to 33. Scilly's renowned visibility means you can often take in the full scale of the wreckage from a distance — a rare privilege on a deep UK dive. Listed among Divernet's 100 Best UK Wreck Dives, this is a site that rewards experience and careful gas planning.
The undisputed queen of the Sound of Mull, the Hispania draws divers back season after season. This Swedish cargo steamer ran aground on Sgeir Mor reef in December 1954, settling upright with barely a list. Sixty-plus years of immersion have transformed her into an underwater garden — every surface encrusted with plumose anemones, dead-mans fingers, and jewel-like tunicates that glow under torchlight. Her holds still yawn open, inviting careful exploration among the remnants of sheet metal and rubber cargo. The engine room remains navigable for those with penetration experience. Normally buoyed and sitting just inshore of the channel marker, she is one of the easiest signature wrecks to find in Scottish waters. Dive her at slack and she rewards you with a display of marine life few temperate wrecks can match.
Scattered in a zig-zag pattern across a shelving slope from 6 to 36 metres, the remains of the SS Iberian tell the story of an 1885 grounding that all 53 crew survived. This iron cargo steamship of 2,930 GRT, built in 1867 with compound inverted engines of 350 HP, was carrying cattle from Boston to Liverpool for F. Leyland & Co. when thick fog delivered her onto rocks half a mile south-west of Bird Island in Dunmanus Bay. The captain and crew escaped in four boats -- three landed on Bird Island rocks, the fourth was swept away but later found with everyone alive. The wreck is broken into multiple sections; the iron propeller remains intact at 30-38 metres. Featured in Divernet Wreck Tour No. 42, the site is accessed from Schull or Crookhaven with no significant currents.
Walk into Kehoe's Pub in Kilmore Quay and you'll find the bell. An excellent model of the Idaho sits alongside it, commemorating the iron-hulled sailing steamer that ran aground on Coningmore Rocks off Great Saltee Island in dense fog on 1 June 1878. Built by Palmers of Jarrow for the Liverpool & Great Western Steam Company, the 3,500-ton Idaho was carrying 151 passengers, 51 horses, cattle, and 1,000 tons of beef from New York to Liverpool. She drifted off the rock and sank within 20 minutes, but remarkably every soul aboard was rescued. The collapsed wreckage sits on bright sand at 15-25 metres and is one of the main dive sites around the Saltees. An anchor stands at the Kilmore Quay marina gate. Strong and unpredictable tidal currents demand neap-tide diving.
Father and son died together. Quartermaster Timothy Buckley of Blarney Street and his son Florence, a trimmer, were both serving aboard the SS Inniscarra when a German submarine torpedoed her on 12 May 1918, ten miles south-east of Ballycotton Island. Their deaths were part of a devastating pattern: in 1918 alone, the City of Cork Steam Packet Company lost the Inniscarra, the Innisfallen, the Imber, and the Serula. By the Armistice, only one ship remained and over 178 employees were dead. Built by Wigham Richardson & Sons Ltd, the Inniscarra carried cargo on the Cork routes. The wreck lies off the Cork coast near Ballycotton.
Ask any Plymouth diver about their first wreck and chances are they will name the James Eagan Layne. This American Liberty ship was torpedoed by U-1195 off Eddystone Reef in March 1945 — one of the very last U-boat kills of the war — and sank in Whitsand Bay after an unsuccessful tow, mercifully without any loss of life. Lying on sand between 10 and 24 metres, she is shallow enough for newly certified divers yet interesting enough to draw experienced wreck enthusiasts back again and again. The structure teems with life: pollack shoal around the superstructure, conger eels lurk in the hull plating, and spider crabs carpet the decking in season. Sitting just 540 metres from the scuttled frigate HMS Scylla, the two wrecks together make Whitsand Bay one of the most accessible double-wreck sites in British waters.
No wreck off the English coast has welcomed more divers than the Kyarra. Built on the Clyde in 1903 as a luxury liner for the Australian run, she carried 286 passengers in considerable comfort before the Great War requisitioned her as a hospital ship tasked with evacuating wounded troops. On 26 May 1918, heading for Plymouth to collect a thousand injured Australians, a torpedo from UB-57 struck amidships and sent her to the bottom a mile off Anvil Point. Six men died. Discovered in the late 1960s and now owned by Kingston and Elmbridge BSAC, she lies between 18 and 30 metres in waters that regularly deliver good Dorset visibility. Thousands of divers visit each year, yet her 127-metre hull absorbs the traffic easily. The boilers, engine room and stern section are highlights, and the marine life — from nudibranchs to cuttlefish — is outstanding for a Channel wreck.
Twenty-five bars of gold remain unaccounted for. Between 1917 and 1924, Royal Navy salvage divers recovered 3,186 of the 3,211 gold ingots carried by the SS Laurentic -- 43 tonnes of bullion worth GBP 5 million at the time, financing British war purchases in North America. The White Star Line passenger liner, converted to an Armed Merchant Cruiser, struck two mines laid by U-80 off Fanad Head on 25 January 1917, sinking with the loss of 354 lives in temperatures of minus 9 degrees Celsius. The wreck at approximately 40 metres off Lough Swilly is heavily collapsed from both natural deterioration and years of intensive salvage. A prominent upright deck gun sits among the tangled wreckage and serves as the key landmark for divers. Part of the extraordinary concentration of wrecks off Malin Head that makes Donegal a premier technical dive destination.
Chased by a U-boat, a Chinese crew made a desperate choice. In 1917, while evading a German submarine near the Saltee Islands, the SS Lennox struck rocks behind Great Saltee Island and went down. Her Chinese crew swam to the island and then onward to Kilmore -- all surviving. The broken wreckage lies at 10-18 metres in sheltered water behind Great Saltee, marked by a buoy. Two large boilers rise to within 5 metres of the surface -- the most prominent features of the dive. The bow is still recognisable, pointing seaward, and a three-cylinder engine is visible among the wreckage. Conger eels inhabit the broken structure. At 107 metres long, the Lennox was built in 1895 and is now one of the most accessible wreck dives from Kilmore Quay, suitable for novice divers.
Twenty-eight hours on a hatch cover. That was how 46-year-old John Carley from Wexford Town survived the sinking of the SS Lismore -- clinging to debris in open sea until he washed ashore, the sole survivor. All 18 crew members drowned when this City of Cork Steam Packet Company cargo ship sank off Hook Head on 11 July 1924, carrying cattle and Ford Motor Company parts from Cork to Liverpool. The wreck lies at 35-38 metres and is regularly dived by Hook Sub-Aqua Club, who marked the centenary in 2024 by placing a memorial plaque on the wreck. A commemorative ceremony was held at Kilmore Quay where relatives of the lost crew handed the plaque to the divers. Boat dive from Kilmore Quay or Slade Harbour.
First blood from the Berlin minefield. On 23 October 1914, the German auxiliary cruiser SMS Berlin laid 200 mines off northwest Ireland on her very first wartime mission. Four days later, the SS Manchester Commerce sailed straight into them while bound from Manchester to Quebec. Fourteen crew died including the Master. On the same day, the same minefield claimed a far more famous victim: the dreadnought battleship HMS Audacious. The Manchester Commerce, a cargo steamship of 5,363 GRT built by Furness Withy & Co., rests at 83 metres -- a deep technical dive requiring trimix, accessed by a long boat transit from the Donegal coast. One of the deeper Malin Head wrecks, demanding extensive deep diving experience.
Beneath the boilers, conger eels the size of your arm wait in the darkness. The SS Marlay is a moody, atmospheric wreck -- dark conditions, poor visibility, and the constant sense that you are not alone down here. This 800-ton steel collier, built in Belfast in 1890, sank in a December 1902 storm when heavy seas breached the hatches on her coal holds. Fifteen of 16 crew perished. She lies on her side at 25-35 metres, hull fairly intact, approximately 5.8 kilometres northwest of the Baily Lighthouse on Howth Head. Three boilers show at low tide. Lobsters, crabs, whiting, and bib populate the wreck alongside the resident congers. Care is needed around holes in the hull -- accidental entry is a real risk. The boat dive from Dun Laoghaire crosses the Dublin Port shipping lane.
The Missouri holds a special place in Anglesey diving — she is the largest vessel ever wrecked close inshore on the island's west coast, and one of the few worthwhile wrecks you can reach by wading in from a sandy beach. A March blizzard in 1886 drove this Warren Line barque-rigged steamer ashore at Porth Dafarch with a cargo manifest that reads like a Victorian general store: live cattle, thousands of cotton bales, sacks of flour, hides, and palm oil. Her remains now lie in two main sections across the bay, the forward part in the middle and the stern hard against the western cliffs, all at an easy 14 metres or less. The shore-dive access from Porth Dafarch beach makes her ideal for newly qualified divers looking for their first proper wreck experience, while the sheer scale of the debris field — from a ship of over 5,000 tons — gives experienced divers plenty to explore on repeat visits.
The most intensively dived wreck on Cornwall's notorious Manacles reef, the Mohegan's story remains one of British maritime history's enduring puzzles. She was barely six months old when she ploughed onto Vase Rock in October 1898, killing 106 passengers and crew on what should have been a routine Atlantic crossing. No one has ever convincingly explained why the ship was so far off course. Today her boilers rise from 22 metres as the centrepiece of a richly colonised underwater landscape, while the skeletal hull frames create a striking grid that draws photographers from across the UK. The site splits naturally into two dives — the boiler section and the bow area — and the surrounding reef teems with life that makes any bottom time spent waiting for slack water utterly worthwhile.
The Moidart's story is one of the most harrowing of the U-boat war. On 9 June 1918, this schooner-rigged steamer was carrying 1,550 tons of Welsh coal and 80 tons of steel plates from Cardiff to Le Havre when UC-77's torpedo struck to starboard near the stern gun. She went down by the stern in less than sixty seconds — so violently fast that not a single lifeboat could be launched. Fifteen of her twenty-one crew perished, many trapped below or thrown into the water alongside the ship. Only six men survived. She rests at 33 metres in Lyme Bay with her bow pointing just east of north, a sombre but compelling dive that puts you face to face with the human cost of unrestricted submarine warfare. The depth and exposed position demand respect, but for advanced divers comfortable in these conditions, the Moidart is a powerful experience.
Copper ingots weighing 40 kilograms each -- some are still down there, visible but stubbornly immovable. The SS Oswestry was a 2,419-ton steel steamship wrecked in fog on the north side of Mizen Head on 12 March 1899, carrying cotton, deal, Indian maize, and valuable lead and copper bars worth approximately 250,000 euros in modern terms. Captain Wilson and all 24 crew were saved by locals. The wreck at 15-20 metres is wedged against a towering rock stack 500 metres north of Mizen Head, making it easy to find. Described as one of the most impressive rummage dives imaginable, the site is littered with copper and lead bar cargo debris. Sometimes mistakenly called the Irada, which was actually a different ship wrecked at Mizen Head in 1908. Built in 1888 by E. Withy & Co., West Hartlepool.
Originally launched in the closing months of World War I as War Buffalo, the Persier spent her interwar years under the Belgian flag before the next conflict caught up with her. In February 1945, a torpedo struck her port side while she sailed in convoy just three miles from Eddystone. She limped into Bigbury Bay and grounded on a reef, where she remains today between 18 and 28 metres. Discovered in 1969 by Plymouth Sound BSAC members, she became a closely guarded local favourite before word spread to the wider diving community. At nearly 122 metres long she is a substantial wreck, and the virtual absence of tidal current at the site means she can be dived at any state of tide — a rare luxury on the Devon coast. Her hull sections, boilers and machinery provide hours of exploration across multiple dives.
Ninety seconds. That was all the time between the torpedo impact and the Pinto disappearing beneath the Atlantic. She was doing what rescue ships do -- stationary, picking survivors from the water after U-482 had torpedoed the SS Empire Heritage just 30 minutes earlier. The same U-boat fired again, and the 1,346 GRT convoy rescue ship sank almost instantly. Captain Lawrence Boggs, M.B.E., was among the dead. Built in 1928 and converted for rescue service in May 1942, the Pinto had sailed with 10 convoys before her loss on 8 September 1944 while stationed with Convoy HX 305. The wreck at approximately 66 metres lies near the Empire Heritage wreck site, north-northeast of Tory Island. A deep technical dive requiring trimix, in remote open Atlantic conditions.
Not all U-boat captains were merciless. On 5 June 1918, SM U-96 surfaced three nautical miles northeast of Lambay Island and fired a warning shot across the bows of the SS Polwell, a British cargo steamer carrying coal from Troon to France. The crew of 30 abandoned ship in two lifeboats. Only then did the submarine fire a single shot amidships, sinking the Polwell. All crew survived, landing at Rockabill lighthouse off Skerries an hour later. The wreck at approximately 30 metres is broken into three sections, with the bow detached from the rest of the vessel. Surveyed by INFOMAR as part of marine heritage documentation of WWI wrecks in the western Irish Sea. An 86.6-metre coal carrier with an unexpectedly humane story.
Artillery shells still lie in the gullies. Scattered to the west of the main wreck site off Great Blasket Island, these munitions from the SS Quiebra's wartime cargo are a stark reminder of what this ship was carrying when she went down. The WWI munitions steamship lies at 15-27 metres on the north face of the island at Lochar Rock, well broken up but with boilers standing upright and the recoil spring of a ship's gun visible among the wreckage. Despite the exposed Blasket location, the site is relatively sheltered from prevailing winds, making it a reliable dive option on Blasket trips. About 45 minutes by boat from Dingle Harbour and often combined with dives at Seal Cove, where playful grey seals steal the show.
Few wrecks carry the emotional weight of the Rohilla. This Harland & Wolff-built liner had been requisitioned as a hospital ship just weeks into the First World War and was steaming south from Scotland to collect wounded soldiers from France when a northeast gale drove her onto Whitby Rock in the early hours of 30 October 1914. With shore lights blacked out for wartime, her crew never saw the reef. What followed was a three-day rescue drama that gripped the nation — lifeboats launching repeatedly into mountainous seas, spectators lining the cliffs, and 83 lives lost despite extraordinary courage from the rescuers. Most of the dead were doctors and nurses. Today the wreck lies flattened in shallow water off Saltwick Bay, accessible as a shore dive when conditions allow. The site is a war grave. At low spring tides, structural remains break the surface — a stark reminder visible to anyone walking the coastal path above.
There is nothing quite like dropping onto the Rondo for the first time. This former wartime standard cargo ship — originally launched as War Wonder — sank in a January storm in 1935 and came to rest on a steep cliff face at an angle of roughly 35 degrees. The result is one of the most visually dramatic wreck dives in British waters: the rudder post breaks the surface at just 5 metres while the bow is buried in sediment at 50. Descending along her hull feels like walking down a tilted skyscraper draped in white plumose anemones and orange soft corals. Every surface pulses with life. The dive demands respect — buoyancy control must be precise, and the depth range means careful gas planning — but the payoff is a wreck experience that stays with you long after the drysuit is hung up. Normally buoyed, she is the showpiece of any Sound of Mull trip.
A New Zealand-owned ship, requisitioned by Britain, torpedoed by Germany, resting off Ireland. The SS Roscommon was an 8,238 GRT cargo steamship built in 1902 by Workman, Clark & Co. in Belfast for the Union Steamship Co. of New Zealand. Taken up under the Liner Requisition Scheme during World War I, she was intercepted by U-53 under Kapitanleutnant Hans Rose on 21 August 1917 while on voyage from Manchester to Australia, approximately 20 miles northeast of Tory Island. No casualties were reported. At 76 metres, this is one of the deeper Malin Head technical dives. A rebreather is the weapon of choice and trimix is mandatory. Mevagh Dive Centre in Carrigart is the specialist operator for the area.
Christmas Day 1900. A Japanese crew, a Chinese cook, Scottish officers, and a steam-powered bucket dredger bound for Formosa. The SS Sente had been built at Greenock for the Japanese government at a cost of 20,000 pounds. Just three days out of port, a winter gale in St George's Channel gave her a fatal list to port. Captain Jameson pointed the vessel for shelter at Cork, but she went down off Roches Point. The hull is barely recognisable at 28-30 metres, but all the heavy machinery remains -- massive drive gears, an upturned engine base with gearbox, dredger buckets, bevelled gears, and propeller shaft sections. The wreckage piles up at a high point rising 4 metres above the seabed. Featured in Divernet Wreck Tour No. 178. Accessible from Crosshaven, with slack water diving recommended.
Lost to memory for the best part of a century, the Shuna was rediscovered in the 1990s and quickly became a favourite among visiting dive groups. Built in Holland in 1909 for a Scandinavian owner, she was carrying coal and iron from Glasgow to Gothenburg when she struck Grey Rock in a storm. Sitting upright less than 200 metres from shore, her position in a small mainland bay shields her from the worst of the Sound of Mull's notorious tidal streams, making her a more relaxed proposition than many neighbouring wrecks. Non-ferrous salvage in the years after her rediscovery opened up the structure, but there is still plenty to see between 16 and 32 metres: deck fittings, coal remnants in the holds, and a resident population of wrasse and conger eels that have made her framework their home.
The P&O cargo liner Somali was bound for Hong Kong with nine thousand tons of wartime supplies — everything from medical kits and batteries to toy lead soldiers and coins for the colony's banks — when Luftwaffe Heinkels found her off Beadnell in March 1941. Bombs ignited her holds, and the resulting explosion broke the ship in two. She settled upright in 29 metres, and her upstanding quadruple-expansion engine has become the defining image of Farne Islands wreck diving. Four cylinder heads rise above the surrounding structure like industrial sentinels, while five boilers arranged in neat rows forward give scale to what was a substantial ship. Marine growth has transformed every surface into a living wall of colour. Accessed from Seahouses or Beadnell, the Somali demands respect for her depth and the tidal window, but she repays it with a dive that regularly appears on lists of the best wreck experiences in North East England.
Undiscovered for over 90 years. The 295-ton London cargo steamer SS Thames struck St. Patrick's Rock off Kilcummin Head in fog on 5 March 1893 while carrying guano from London to Sligo. She backed off the rock into deeper water and sank at 24 metres. All 12 crew were saved. The wreck then vanished from memory until 14 September 1984, when Castlebar Sub-Aqua Club located her at the very same rock. Built in 1860, this Victorian-era steamer and her cargo represent a snapshot of 19th-century coastal trade along the Irish west coast. An intermediate boat dive in the sheltered waters of Killala Bay, now joined by the nearby MV Shingle artificial reef.
Small but full of surprises, the Thesis has a story unlike any other wreck in the Sound of Mull. This iron screw steamer went down in October 1889 carrying pig iron, and for decades she lay forgotten on a sloping shingle seabed. In the 1970s, salvors arrived not for treasure but for her hull plates — pre-nuclear iron, free from the background radiation that contaminated all steel produced after the first atomic tests. That salvage stripped her bare, but in doing so it created an unusually open wreck where framework ribs, deck beams and cargo holds are all exposed to exploration. The pig iron remains scattered throughout. Sitting upright on her keel between 14 and 32 metres, she offers an intimate, manageable dive that pairs perfectly with the bigger wrecks nearby. Dive at slack water for the best experience.
No shipwreck in British waters had a greater impact on environmental policy than the Torrey Canyon. When this Liberian-flagged supertanker struck Pollard's Rock on the Seven Stones reef in March 1967, she released roughly 120,000 tons of crude oil into the sea — the worst spill the UK had ever seen. The government's desperate response included RAF bombing runs with napalm to incinerate the remaining cargo, an operation watched by millions on television. The disaster rewrote international maritime law and birthed the modern framework for oil pollution response. Diving the remains demands expedition-level planning: Seven Stones lies fifteen miles west of Land's End in open Atlantic, where settled weather windows are rare and brief. Those who reach the scattered wreckage find it spread across a reef alive with marine growth, the steel slowly yielding to the ocean that made the Torrey Canyon a household name.
Captain Tolson and 18 men rowed 12 miles to Killiney Bay. Every one of them made it. On 13 January 1876, their ship -- the 478 GRT iron merchant steamer SS Vesper, laden with 620 tons of coal and sugar bound from Glasgow to Dunkirk -- had run aground on the Kish Bank and broken in two. Built by Courlay Bros of Dundee in 1865 for Huntley & Berner of Glasgow, the Vesper now lies at an estimated 10-15 metres on the shallow bank, approximately 11 kilometres off the Dublin coast. A protected archaeological site with LIVE status, the wreck provides a welcome oasis of marine life on the otherwise featureless sandy bank. Frequently dived alongside the nearby Bolivar. Boat dive from Dun Laoghaire, subject to tidal currents.
If there is a gateway wreck on the Lizard Peninsula, the Volnay is it. Nearly every visiting dive club makes her their first target, and for good reason — she sits at a forgiving 18 to 22 metres with enough structure to keep things interesting without demanding heroics. A German mine from UC-64 ended her war service in December 1917 while she carried Canadian ammunition south past the Manacles. Her two great boilers now anchor the site, rising from silty sand that conceals wooden ammunition boxes, scattered bollards, and chain. Pink sea fans have colonised the higher wreckage, adding unexpected colour to a scene that might otherwise be all rust and silt. The combination of accessible depth, reliable marine life, and a genuine wartime story makes the Volnay the wreck that hooks new divers on the Lizard.
Barrels of Guinness saved their lives. When the SS W.M. Barkley -- the first vessel of the famous Guinness fleet -- was torpedoed by UC-75 on 12 October 1917, she broke in two and sank within minutes just seven miles east of the Kish Lightship. Five crew died including the captain. But eight survivors escaped in an open lifeboat, buoyed by floating hogshead barrels of stout from the breached cargo hold. Built in 1898 and sold to Guinness in 1913, the 569 GRT vessel was also the first Irish merchant ship defensively armed with guns against submarine attack during WWI. The wreck lies at approximately 55 metres about 16 miles east of Dublin Port. A historically significant wreck connecting Dublin's brewing heritage with the submarine warfare of the Great War.
Ornate ironwork on the bow, intact after more than a century on the seabed. The SV Invercauld (III) was a 1,416 GRT three-masted steel barque, 237.5 feet long, attacked by the German submarine U-84 on 22 February 1917 while carrying timber from Gulfport, Mississippi, to Fleetwood. After sustaining damage approximately 22 miles southeast of Mine Head, she drifted and sank just south of the Coningmore Rocks near the Saltee Islands. The wreck sits remarkably upright at about 25 metres and is discernible throughout her entire length -- one of the most structurally intact wrecks in the Saltees group. The boilers rise 4 metres off the seabed. Strange and unpredictable currents make this a dive for adequately trained divers only; the current on the shot line may differ significantly from bottom conditions.
Somewhere in six metres of water off Hook Head, walrus tusks may still lie among the wreckage. The SV Royal Arthur ran aground in 1850 carrying this unusual cargo, and while tusks have been found over the years, some are thought to remain hidden in the scattered debris on the west side of the peninsula. This is a shore dive straight off the camping area -- about as easy as wreck diving gets. But the real draw may be what surrounds it: the extraordinary underwater caverns along Hook Head's western shoreline, where sunlight penetrates through blowholes to create dramatic cathedral-like illumination. Strong tidal currents around the headland require slack water diving. A unique combination of historical curiosity and natural spectacle.
You can see it from the cliff walk above -- and then swim through it below. The Samson is a 55-metre Maltese crane barge that washed ashore at Ram Head, Ardmore, during a south-easterly gale on 12 December 1987 while being towed from Liverpool to Malta. The towline parted off the Welsh coast and could not be reconnected. The crew of two were rescued by RAF helicopter from Brawdy. Despite questions in Dail Eireann about removing the wreck, it was never salvaged. In April 2016 the entire crane jib collapsed into the sea, adding to the underwater wreckage. The site offers shallow diving and snorkelling from 5 to 16 metres and has become a popular local dive -- shore or boat access from Ardmore. An evolving, accessible wreck in a scenic location.
Only one person survived: a boy named Giovanni. The Santa Maria de la Rosa, Vice Flagship of the Guipuzcoan squadron of the 1588 Spanish Armada, entered Blasket Sound already battered from earlier engagements, seeking shelter behind Great Blasket Island. She lost her anchor and struck Stromboli Reef, sinking instantly. The wreck was rediscovered on 4 July 1968 by Sydney Wignall and Colin Martin -- making it the first Armada wreck to receive proper scientific investigation and the site of the first large-scale swimline search in the British Isles. Archaeological remains at 35-40 metres on flat shingle include a mound of ballast stones with parts of the lower hull and main mast step. A pewter plate inscribed "matute" helped identify two crew brothers. Protected archaeological site; permission required. Strong tidal currents in Blasket Sound make this a challenging technical dive.
Forget the trawler wreckage for a moment. What makes this site extraordinary is what lies alongside it -- an interconnected cavern system beneath the Hook Head promontory, lit by shafts of sunlight streaming through blowholes above. The Schlesien's scattered remains sit on the west side of the peninsula in 5-10 metres, and they provide a useful focal point for what is really a combined wreck-and-cave shore dive. Cathedral-like lighting fills the chambers as the sun moves overhead. Tidal currents require slack water timing, but the shallow depth and shore access make this ideal for less experienced divers who want something more memorable than a typical training dive. Easily combined with the nearby SV Royal Arthur site.
A Greek steamer laden with Black Sea grain, the Spyridion Vagliano met the same fate as so many vessels on the Manacles — a navigational miscalculation that put her squarely onto Maen Voes on a February night in 1890. Fourteen of her twenty-two crew were lost to the freezing water. She now lies close to the more famous Mohegan, reachable by following a south-west compass bearing from that wreck down to around 18 metres. What sets her apart is the boiler: with its outer casing long since rotted away, the internal tube structure is exposed in unusual detail, offering a cross-section lesson in Victorian marine engineering. In summer the wreckage disappears under dense kelp, so spring and autumn visits tend to reward with clearer views. The site makes a natural second dive when paired with the Mohegan on a Manacles boat trip.
The St Andre arrived at the Farne Islands the hard way — hitting the Crumstone rock in October 1908, briefly floating free, then settling permanently at Staple Island with a belly full of pig iron. That dense cargo ensured she went down quickly and stayed put, and the heavy iron ingots still litter the seabed around the main wreckage like industrial confetti. At 17 to 25 metres, the site sits in a comfortable depth range for intermediate divers and makes a reliable second or third dive on a Farne Islands boat trip out of Seahouses. Above the surface, Staple Island hosts one of the archipelago's densest seabird colonies — guillemots, razorbills, and puffins in season — so the boat ride out is half the experience. The combination of accessible wreck diving and extraordinary wildlife is what draws clubs back to the Farnes year after year, and the St Andre is a dependable part of that roster.
Curious blennies watch you from every crevice. The Nellie was a Dutch trawler that foundered at the Sovereign Islands near Kinsale in the 1960s -- reports on how she was lost are conflicting, with one account blaming a storm on the Liverpool-to-Cork run and another claiming no lives were lost. What's not in dispute is the charm of this dive. At approximately 15 metres on the south side of Big Sovereign island, tilted decks and rusting masts sit in turquoise waters teeming with marine life. Suitable for all grades of diver, this is a lovely wreck to potter around on a short boat trip from Kinsale. The anchor was raised by local divers and now stands at the top of the slip in Oysterhaven, serving as both memorial and a warning to seafarers approaching the rocks.
She nearly changed the course of the war. U-2511 was the only operationally deployed Type XXI "Elektroboot" submarine in World War II -- the revolutionary design that could have devastated Allied shipping had it entered service earlier. Commanded by Korvettenkapitan Adalbert Schnee, she made one war patrol and had a British cruiser group in her sights before the ceasefire aborted the attack. Surrendered at Bergen, Norway, she was scuttled by Royal Navy gunfire on 7 January 1946 during Operation Deadlight after her towing cable parted. Discovered in 1999 by local diver Al Wright, the wreck at 67-69 metres off Malin Head is largely intact on her port side, with a large blast hole on the starboard side near the conning tower. One of the most historically significant U-boat wrecks anywhere. Featured on BBC Dig WW2 with Dan Snow.
At 43 metres on a rocky seabed near Baltimore, a German U-boat sits almost perfectly intact -- torpedoes still loaded in their tubes, the periscope glass unbroken, the Walter snorkel standing upright after eight decades on the bottom. U-260 was a Type VIIC submarine that struck a British mine approximately 32 kilometres south of the Fastnet Rock on 12 March 1945. The entire crew survived and were interned in Ireland for the rest of the war. Apart from mine damage to the bow, the hull is remarkably preserved. Open hatches allow limited penetration. The conning tower, twin bronze propellers, and DF aerial all remain in place. Visibility ranges from 5 to 10 metres. For advanced divers visiting Baltimore, West Cork, this is an unmissable dive -- compact enough to navigate the entire submarine in a single outing.
Tucked against the east shore of Rysa Little, the V83 is a footnote to the great scuttling that became a dive site in its own right. When the order came to open the seacocks on 21 June 1919, British sailors boarded this torpedo boat destroyer and ran her aground before she could sink. Ernest Cox later pressed her into service during his audacious campaign to raise the battleship Hindenburg, and an unsuccessful attempt to refloat her in 1926 left her where she sits today — upright on a gentle slope, broken into two halves. The bow section is fragmented in about eight metres; the stern sits more recognisably in 15 to 16. There is rarely any current, and the maximum depth barely troubles a single-cylinder pony bottle. For divers arriving in Orkney with basic qualifications, or veterans looking for a gentle warm-up, the V83 is an ideal introduction to Scapa Flow — a bite-sized piece of the same history that lies in the deep water beyond.
Resting in the shallow waters of Studland Bay lie seven Valentine infantry tanks — silent witnesses to the deadly rehearsals that preceded D-Day. In April 1944, during the top-secret Exercise "Operation Smash," these tanks were testing duplex-drive swimming modifications that would allow armour to float ashore on the Normandy beaches. The trials went tragically wrong: all seven sank, and six soldiers lost their lives. Today the tanks sit between 8 and 16 metres, encrusted with marine growth and surrounded by an ecosystem that has made them its own. Two are permanently buoyed and spaced roughly five metres apart, making them easy to locate. As a Scheduled Ancient Monument, the site carries strict legal protections — look but do not touch. For divers of any level, swimming alongside these D-Day training relics is a moving and accessible encounter with one of the war's lesser-known tragedies.
