MEFJORD (POSSIBLY) - Cornwall & Devon

The Mefjord, a steamship sunk by a U-boat in 1918, is one of those wrecks we keep coming back to off the Devon coast. At 39 metres, it’s a proper dive, certainly not for beginners, but it rewards you with atmosphere. Descending, the hull emerges from the green murk, usually with a good run of vis, revealing its broken structure. What we love here is the sheer sense of history. You can still trace the outline of the decks, see the two boilers standing proud, and push into the engine room if you’re comfortable with overhead environments. Shoals of bib and pollack shimmer around the superstructure, and we’ve often spotted conger eels tucked into the deeper recesses. It’s a beautiful wreck, encrusted with anemones and dead man's fingers, a real deep dive classic for those who appreciate the slower pace of UK wreck diving. We'd suggest hitting it on slack water, it makes all the difference.
