HMT JASPER - Scapa Flow, Orkney

The HMT Jasper sits deep in Scapa Flow, a trawler-turned-minesweeper that met its end during wartime. At 58 metres, this is one for the technical diver, and honestly, a site we think is often overlooked for its bigger, more famous neighbours. She's a smaller wreck, just over 30 metres long, but what she lacks in size, she makes up for in atmosphere. We love descending onto her deck, where the visibility often holds a green hue, making the structure appear out of the gloom. Her triple-expansion engine is still very much in place, a solid chunk of metal standing proud, and you can swim through areas of the superstructure. It's a real hands-on wreck, not just something to circle. Look closely and you'll spot dead man’s fingers clinging to the metalwork, and the occasional ling or large cod sheltering inside. The lack of current down here usually means a peaceful dive, allowing you to really take your time exploring the details. It's an honest piece of history, and for us, a truly rewarding dive for experienced cold-water wreck enthusiasts. Just be mindful of your bottom time at this depth.
