ADC 527 (POSSIBLY) - Northumberland & Northeast

ADC 527, or ‘Possibly’ as it’s often known, is a deep-water wreck off the Northumberland coast. We love a dive with a bit of history, and this one certainly delivers. Sunk in 1946, this 57-meter vessel went down with a full cargo of unfused 75mm shells and fuses. It’s still considered dangerous, and for good reason – you’ll spot those shells scattered across the seabed and inside the wreck, a stark reminder of its past. Dropping down to 37 meters, the visibility can be variable here, but when it’s good, the structure is impressive. We've had some cracking dives exploring the holds, seeing how the local marine life has really taken over. Expect to find plenty of crabs and lobsters tucked into every nook, with schools of coalfish often circling the main structure. It’s a dark dive, requiring good lights to really appreciate the details and the atmosphere. This site is best suited for experienced cold-water wreck divers comfortable with deep diving and potential currents. Our tip? Aim for slack tide; it makes a big difference to the enjoyment.
