    StandoutExceptional marine biodiversity

    The Maplefield, lost in 1945, is more than just another wreck off the Cornish coast. At 55 metres, this steamship is a serious deep dive, definitely not one for the casual explorer. We love how intact she is, especially for her age and depth. Dropping down, you’ll first pick out the stern, with the propeller still in place, often shrouded in a shoal of pout. Work your way forward and the triple expansion engine is a highlight, standing proud and still recognisable, a testament to her builders in Lytham. Our favourite part is the bow, often home to conger eels peeking out from behind the plates. The visibility here can be tricky; sometimes it’s a gin-clear 15 metres, other days it’s closer to five, making a good light essential. We’d suggest diving her on a slack tide, which can be short, so good dive planning is key. This is a dive for experienced technical divers, those who appreciate history and a wreck that still feels like a ship, not just a pile of scrap.
