    Diving the Strathgarry feels like stepping into a cold, dark history book. She's a trawler, sunk in 1915 after a collision, and sits upright at 55 metres, a truly imposing sight. We love the bridge area; it’s largely intact and gives you a real sense of her working life before she became a boom defence boat. The descent is typically dark, typical Scapa Flow, but then the shape slowly resolves from the gloom. You’ll often find large wrasse hovering around the mast, and the decks are covered in colourful anenomes and hydroids – a surprising splash of colour against the grey steel. For photographers, the stern provides some fantastic wide-angle shots, especially if you can catch a glimpse of natural light filtering through from the surface. We’d suggest a trimix certification for this one; it’s a deep dive, and the bottom time is precious. The Strathgarry is a proper expedition into Scapa's past.
