ULL (PROBABLY) - Cornwall & Devon

The ULL, formerly known by a string of names like Tosca and Peritia, is a proper deep dive off the coast of Cornwall. At 46 metres, it’s certainly not for the casual diver; this is one for those with the training and comfort at depth. We love the history here, imagining this steamship, built in Flensburg back in 1880, finally coming to rest in 1917. What you get is a coherent wreck, still largely intact despite its age and depth. We find the single boiler a real focal point, and the compound expansion engine is still recognisable, a testament to its sturdy build. Visibility can be a challenge, as with many UK wrecks, but on a good day, the ULL reveals itself through the silty water, draped in anemones and dead man's fingers. Ling often lurk in the shadowed corners, and you might spot a few dogfish resting on the deck plates. It’s a quiet, reflective dive, feeling the chill of the deep, a tangible connection to maritime history. Come prepared for the cold and the depth, and you’ll find a rewarding exploration here.
