GRAYFISH - Scapa Flow, Orkney

The trawler *Grayfish* is one of Scapa Flow's lesser-dived wrecks, often overlooked for the big German fleet, but we think that’s a mistake. Sunk in 1973, she sits upright in about 25 metres, and the visibility here can be surprisingly good, especially on a settled day. What we love about *Grayfish* is her intactness. You can still see the trawl gallows, the winch, and the wheelhouse structure. Swimming through the hold, you’ll often find conger eels tucked into corners, their thick bodies camouflaged against the rust. Keep an eye out for inquisitive wrasse darting in and out of the plating and the sheer number of squat lobsters clinging to every surface. It’s a proper wreck, one where you get a real sense of its working life before it went down. This site is perfect for anyone looking for a relaxed dive on a solid, explorable wreck, away from the bigger crowds.
