    The HMS Unicity, what’s left of her anyway, is a curious dive on the Scottish East Coast. We’re talking about a shallow wreck, just 6 metres deep, and that’s a big part of its charm. She was a minesweeper that capsized back in ‘42, and while the bulk of her was salvaged a year later, there’s still enough scattered across the seabed to make for an interesting rummage. You’re not going to see a pristine, intact ship here. Instead, picture fragmented metalwork, twisted girders, and scattered plates, all colonised by a surprising amount of life given the depth. It’s the kind of site where you’ll spend your time poking into nooks and crannies, discovering where the wrasse are hiding or spotting small crabs scuttling amongst the wreckage. Visibility can be hit or miss, as is tradition for these parts, but on a good day, the light plays beautifully through the suspended particles, illuminating the green growth on the metal. This site is perfect for newer wreck divers or anyone who loves a good historical hunt without the challenge of depth or strong currents. It's a great second dive of the day, a relaxed exploration rather than a deep penetration.
