    The Pentland Firth, a trawler sunk by a mine in 1918, feels like a proper piece of history down in Scapa Flow. It’s not one of the massive German fleet wrecks, but that’s precisely why we love it. The scale is more intimate, allowing you to really get a feel for the vessel. We’d suggest dropping onto the stern, which sits upright, before working your way forward. You’ll find the bow section a bit more broken up, but still incredibly atmospheric. Inside the holds, the light-bulb sea squirts glow with an ethereal quality, clinging to the bulkheads. Common lobsters often peer out from crevices, their antennae twitching in your torch beam. Look closely for jewel anemones painting the metalwork in flashes of orange and pink. It’s an ideal dive for those who appreciate exploring a compact wreck, where you can easily navigate without feeling overwhelmed, perfect for photographers or divers looking to truly connect with a piece of the past. Just remember your drysuit; this is Orkney, after all, and the chill adds to the historical weight.

    Safety Notes
