Wreck of Mary Croan

The Mary Croan might not be the most famous wreck in Scapa Flow, but she’s one we return to time and again. We love her because she’s so accessible, sitting in shallower waters than some of her colossal neighbours. This trawler, scuttled in 1919, lies largely intact on her port side, offering a fantastic sense of her original form. You'll fin through open holds now home to dense clusters of plumose anemones, their white tentacles swaying gently in the subtle flow. Look for velvet crabs scuttling amongst the plates and the occasional inquisitive wrasse peeking from behind a bulkhead. We'd suggest aiming for a slack tide; it makes navigating the interior much more relaxed. The relatively shallow depth also means you get good ambient light penetration on clear days, illuminating the skeletal structure and making those anemones almost glow. She’s a great wreck for divers wanting to experience Scapa Flow’s history without the demands of a deeper dive, perfect for a long exploration or even a refresher.
