About this site
Carmarthen is the wreck of the SS Carmarthen, a 4,262 ton cargo ship that was torpedoed by SM UC-50 and sunk in 1917. She lies north to south in 18 to 20 metres of water, with plenty of marine life around her.
All three boilers are visible, and most of the broken wreckage stands 3m proud of the bottom. The 12-pdr gun she once carried has gone.
