    The Boston Heron, one of Scapa Flow's smaller, shallower wrecks, often gets overlooked for the behemoth battleships. Big mistake. We think this trawler is a brilliant dive, especially for those looking to get comfortable on a wreck without feeling overwhelmed by scale or depth. She sits upright, pretty much intact, with a visible stern, bow, and wheelhouse. Our favourite part is the wheelhouse, still standing proud, where you can peer through empty windows into the control room. The interior is surprisingly open, letting you explore with natural light filtering through, revealing the slow creep of anemones and dead man’s fingers across bulkheads. Around the deck, we've spotted squat lobsters tucked into crevices and plump wrasse nosing around the superstructure. It's a great spot for honing your wreck penetration skills in a relatively safe environment, and often, the currents here are far more forgiving than on the deeper sites. We’d suggest a slack water dive for the best visibility.

    Safety Notes

    Wreck site - avoid penetration without wreck diving certification. Watch for sharp metal and entanglement hazards.

    Cold water this month (avg 13°C). Drysuit or thick wetsuit (7mm+) recommended.
