    StandoutExceptional marine biodiversity

    The General Leman, for us, is a proper technical dive, and one that absolutely earns its standout status. Lying deep at 52 metres, this sailing vessel from 1918 offers a genuine piece of WWI history off the Cornish coast. Dropping down, the visibility here can be superb on a good day, giving you that thrilling first glimpse of the wreck emerging from the blue. We love how intact sections still stand, giving you plenty to navigate around and peer into. This isn’t a site for casual pottering. You need your trim dialled in and plenty of gas, but the rewards are there. Expect to find conger eels making homes in the deeper recesses, and the structural integrity means there are lots of shadowy nooks where inquisitive divers can shine a torch and spot smaller crustaceans tucked away. It’s a dive for those who appreciate the quiet solemnity of a historical wreck, the challenge of depth, and the thrill of exploring something truly substantial. Our tip: pick a slack tide and a day with minimal swell for the most comfortable descent and the best chance of decent light penetration.
