DEI SEI - Scottish West Coast
The DEI SEI isn't one of those wrecks that jumps out at you, intact and impressive. This is an ancient wreck, sunk back in 1782, and time and tide have done their work. What you find now are the scattered remains of a sailing vessel, nestled on the seabed in the Skerries Roadstead. We love sites like this because they feel like diving through history itself. You’re looking at a low-lying spread, timbers mostly broken down, but still offering plenty to explore if you take your time. Think less grand ship, more archaeological puzzle. We’ve found the real joy here is in the smaller details – the way the occasional rib protrudes, the scatter of ballast stones. It’s perfect for divers who appreciate the subtle beauty of an aged wreck and the life that now calls it home. The holdfasts and crannies are a haven for squat lobsters, and we often spot butterfish darting between the decaying timbers. Visibility can be a bit variable here, so we’d suggest aiming for a calm day and diving around slack water for the best chance to really absorb the atmosphere.
