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) - BOMA offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The Boma wreck, resting at 28 meters, is a proper dive for those who appreciate a bit of history beneath the waves. This steamship, sunk in 1918, lies broken but still recognisable, with those impressive boilers a key focal point. We’ve found plenty of pollack hanging around the metalwork, and the usual crab and lobster tucked into the nooks and crannies. It’s a good choice for divers comfortable with depth and who enjoy poking around a substantial piece of maritime heritage off the Cornish coast. Current can be a factor, so picking your slack water window is always sensible here.
