HMS HARMONY - Scapa Flow, Orkney

The Harmony, a drifter sunk in 1941, might not be the grandest wreck in Scapa Flow, but we love it for its character. Resting upright in 21 metres, it's a perfect dive for exploring machinery and getting a real feel for a working vessel. We always head for the triple-expansion engine, an impressive hunk of metal still standing proud. You can swim around the prop shaft too, which gives a great sense of scale. Visibility here often sits around 10-15 metres, so the wreck emerges slowly from the green, creating an atmospheric dive. Keep an eye out for the resident wrasse darting between the plates and the squat lobsters tucked into every crevice. We think it’s a brilliant site for newer wreck divers or those looking for a relaxed second dive, allowing plenty of time to poke around without the pressure of deeper, more complex wrecks. It’s an honest, tangible piece of history down there.
