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 St Magnus (Possibly) offers some of Scapa Flow, Orkney's richest wreck diving. Water ranges 8-14°C, warmest July, August, September.
The Prudentia isn't the biggest wreck in Scapa Flow, but for us, it's one of the most atmospheric. She's broken up pretty well, lying at an angle with her stern at about 20 metres, and the bow section shallower. We love tracing the length of her, imagining her final moments, especially on a day when the light penetrates the gloom. You’ll find an incredible amount of life here, too. The Devonshire cup corals are just stunning, splashes of orange against the steel, and we’ve seen some huge shoals of sprats and sand eels here, silver ribbons moving as one. Look out for razorbacks tucked into the nooks and crannies. The currents can pick up, so we’d suggest timing your dive for slack water, making the penetration into the deeper parts of the hull a bit more comfortable. It’s a dive that rewards slow exploration, taking in both the history and the vibrant life that has reclaimed it.
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.
