UB 118 - Cornwall & Devon

The UB 118, sitting upright at 60 metres, is a proper technical dive, and one we rate highly for experienced wreckies looking for a challenge off the Cornish coast. Dropping down, the sheer scale of this German U-boat becomes clear. We love how intact she is, especially the conning tower still standing proud. You’ll find the deck guns missing, salvaged long ago, but the torpedo tubes are there, ominous and open, perfect for a torch beam exploration if you’re properly skilled and equipped. The real draw here, beyond the history, is the sheer biomass that's made the submarine home. Conger eels the size of your thigh peer from every crevice, and the hull is draped in dead man's fingers and anemones. Visibility can be hit or miss, but on a good day, the low light filtering through the water column gives the whole site a wonderfully eerie atmosphere. It’s a deep, dark dive, certainly not for the faint of heart, but for those with the training and confidence, it’s a truly rewarding experience.
