Also known as: HMS Guide Me II
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.
On 29 August 1918, during a coastal anti-submarine patrol off Dublin Bay, the Guide Me II was involved in a collision — reports vary as to whether it was with an unnamed vessel or with the Muglins rocks east of Dalkey Island. One crew member was lost in the sinking. The wreck settled upright on a coarse sandy seabed at approximately 33m depth.
Guide Me II is a trawler wreck located off Dublin, Ireland at a depth of 38 metres. The vessel was lost due to Collision in 1918. The wreck is diveable.
Guide Me II lies at 32 to 38 metres depth, 1.5 km SE of the Muglins, east of Dalkey Island.
Guide Me II sank after a collision on 1 January 1918 during World War I, off Dublin, Ireland.
