    There are a few wrecks in Scapa Flow that really capture that sombre, industrial feel, and Prudentia is right up there. This isn’t a pretty wreck in the typical sense, no colourful corals here, but it’s an absolute stunner if you appreciate history and structure. Dropping onto her decks at 23 metres, you’re met with a proper tanker, lying on her port side, well broken but still very much a ship. We love nosing around the engine room, which is often surprisingly accessible, and picturing the crew at work. It's the scale of the Prudentia that gets you; 95 metres of twisted metal, home now to anemones and dense shoals of coalfish that shimmer in the often murky green light. We’d suggest taking your time exploring the bow, where the anchor chain still drapes, and peering into the cargo holds. The visibility here can be a bit variable, so a good torch is essential to cut through the gloom and properly appreciate the details. It’s a dive for those who enjoy a bit of a penetration, or just want to soak in the atmosphere of a true historical casualty.
