GUERNSEY COAST - Cornwall & Devon

The Guernsey Coast sits deep off the Cornish coast, a proper dive for experienced hands. We love this wreck because it’s a time capsule, settled upright on the seabed. Dropping down, you’ll start to pick out the distinct lines of her hull, then the superstructure, often draped in fishing nets, so watch your trim. This isn't a wreck you’ll swim through much, but exploring the deck and her machinery aft is the real draw. Conger eels are always lurking in the darker recesses, and schools of bib and pollack shimmer around the mast structure. It’s a quiet, reflective dive, perfect for those who appreciate the history embedded in steel, rather than chasing quick thrills. Be prepared for cold water, even in summer, and always check the tides – that deep, a strong current can really ruin your day.
