CLEDDY (PROBABLY) - Cornwall & Devon

The Cleddy, or what we’re pretty sure is the Cleddy, is a phenomenal wreck dive off the coast of Cornwall. Dropping to around 39m, it’s one for the experienced wreckies, demanding good trim and confidence in low visibility – which, let’s be honest, is part of the charm in UK diving. This iron steamship, sunk back in 1889, lies largely intact, a real testament to its sturdy build. We love exploring the bow, which points north, where huge schools of bib and pollack swirl, almost clouding out the ambient light. The stern is our favourite, though, for the sheer scale of the propeller and rudder, often draped in plumose anemones, their white tentacles swaying with the surge. You can often see conger eels poking their heads from inside the collapsed hold sections, watching you with an unnerving stillness. It’s a proper dive into maritime history, with every plate and beam telling a story. Best dived on slack water, naturally, to truly appreciate the scale.
