RISOY (PROBABLY) - Cornwall & Devon

Dropping onto the Risoy, you’re hitting a proper deep wreck in UK waters. This old steamship, sunk in 1942, sits upright at 53 metres, its deck just begging for an experienced eye. We've seen conger eels make homes in the deeper sections of the hull, sometimes tucked right into where the triple-expansion engine would have been. Keep an eye out for dogfish resting on the silty bottom nearby. It’s a site for those with solid deep diving certs and a good sense of gas management. The Risoy delivers that satisfying feeling of exploring history, even if the vis needs to be just right.
