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) - BOB offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The BOB, a steamship sunk by a German submarine in 1917, rests off Start Point at a considerable depth, reaching 60 metres. It’s a site for experienced wreck divers comfortable with deeper profiles and the often-cooler UK waters. What we find here is a solid wreck, well-colonised with anemones and dead man's fingers, giving it a real sense of history. You can still make out the ship’s structure, with the occasional lobster peering from a crevice. It’s a rewarding dive for those who appreciate the quiet history of a wartime loss.
