Wreck Diving in United Kingdom
47 diveable wrecks across 13 regions. Depths range from 3m to 62m.
Anglesey(1)
Argyll(7)
MV Akka
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.
MV Tapti
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.
SS Breda
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.
SS Hispania
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.
SS Rondo
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.
SS Shuna
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.
SS Thesis
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.
Cornwall(4)
SS Mohegan
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.
SS Torrey Canyon
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.
SS Volnay
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.
Spyridion Vagliano
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.
Devon(3)
HMS Scylla
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.
SS James Eagan Layne
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.
SS Persier
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.
Dorset(5)
HMS M2
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.
MV Aeolian Sky
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.
SS Kyarra
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.
SS Moidart
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.
Valentine Tanks (Operation Smash)
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.
East Sussex(1)
Isles of Scilly(2)
MV Cita
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.
SS Hathor
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.
Northumberland(5)
MV Acclivity
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.
SS Abessinia
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.
SS Chris Christensen
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.
SS Somali
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.
St Andre
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.
Orkney(10)
F2
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.
SM UB-116
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.
SMS Brummer
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.
SMS Coln
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.
SMS Dresden
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.
SMS Karlsruhe
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.
SMS Konig
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.
SMS Kronprinz Wilhelm
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.
SMS Markgraf
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.
V83
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.
Pembrokeshire(4)
MV Lucy
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.
SS Cambro
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.
SS Dakotian
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.
SS Dalserf
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.

HMS Pathfinder
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.
SS Glanmire
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.

HMS/m A1
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.
SS Gascony
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.
