Why dive here
With 176+ marine species recorded in the area - including blue sharks, dolphins, dwarf minke whales, humpback whales and ocean sunfish (mola mola) - U 390 offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The U 390, a German U-boat sunk in 1944, lies upright in 43 metres of water off the coast. It’s a substantial dive, 67 metres long, still very much a submarine shape. We’ve found the conning tower still identifiable, and the pressure hull is largely intact, though age and depth charges have taken their toll. Expect to see plenty of pollack and conger eels making homes in the dark recesses, along with the usual invertebrate suspects like dead man's fingers. This dive is best for experienced wreck divers comfortable with deep, dark conditions and the chill of the North Atlantic.
