Why dive here
With 140+ marine species recorded in the area - including blue whales, dolphins, dwarf minke whales, humpback whales and ocean sunfish (mola mola) - Wreck of Ruemera offers some of Scapa Flow, Orkney's richest wreck diving. Water ranges 8-14°C, warmest July, August, September.
The Osterhav is pure Scapa Flow magic, a wreck that really rewards a thorough exploration. She lies on her starboard side, about 15m deep, her bow pointing northeast, and even in Scapa's often moody light, her character shines through. We love working our way along her deck, spotting everything from plump lumpsuckers clinging to the plating to the surprising flash of a reddish crab scuttling into a crevice. This isn't just a pile of metal; it’s a living reef. The interior is open enough in places for easy penetration, revealing machinery festooned with anemones. Our favourite spot is the engine room, though you need to watch your buoyancy in there. The Osterhav is perfect for anyone keen on wreck history without the extreme depths or currents of some of Scapa's bigger sites. It's a great second dive of the day, when you're looking for something a bit less demanding but still packed with atmosphere.
