    StandoutExceptional marine biodiversity

    The HMS *Stockforce* is one of those deeper wrecks that really gets our dive team talking. Lying at 60 metres off the coast of Cornwall, this isn’t one for the casual diver. She was a Q-ship, a decoy merchant vessel bristling with hidden guns, torpedoed by a German U-boat in 1918. When you drop down, that history feels palpable. What makes *Stockforce* special for us is the intact nature of her midships. You can still make out the single boiler and the triple-expansion engine, looming out of the gloom. Visibility here can vary wildly, but on a good day, with a bit of ambient light filtering through, the wreck stands proud. We’ve had dives where large conger eels peered from every dark opening, and the occasional inquisitive anglerfish has made an appearance. It’s a proper expedition, demanding solid trimix skills and careful planning, but the rewards are in that tangible connection to wartime history and the sense of diving a truly significant, silent sentinel.
