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) - ST KATHARINE (PROBABLY) offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The ST KATHARINE, or what we strongly suspect is her, offers a deep dive for those comfortable with technical depths off the Cornwall coast. Down at 57 metres, the wreck of this steamship, sunk back in 1917, is largely intact. You'll find her machinery aft, with a single boiler and compound expansion engine making for interesting points of exploration. Despite the depth and low light, she’s become a haven for crabs and various fish species, often darting in and out of the hull structure. We'd suggest this site for experienced wreck divers looking for a challenging dive with a real sense of history.
