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) - INCONNU offers some of Scapa Flow, Orkney's richest wreck diving. Water ranges 8-14°C, warmest July, August, September.
Inconnu is a site that often gets overlooked in Scapa Flow, probably because it’s a modern fishing vessel amongst the giants of the German fleet. But for us, it's a quiet favourite, especially when the weather rolls in and you need a shallower, more sheltered dive. The wreck lies in two main pieces, separated by a gap of maybe ten metres. You’ll first come across the bow section, still quite intact, with the holds offering some easy penetration for those comfortable ducking inside. Look for the resident wrasse darting in and out of the twisted metal. The stern, where the wheelhouse once stood, is much more broken up – a jumble of plating and ribs. This is where we often find the most life. Crab and lobster tuck themselves into every crevice, and the anenomes here are particularly colourful. It’s not a grand, imposing wreck, but Inconnu has a raw, honest beauty. It tells a story of a working boat, not a warship. We find it’s a brilliant second dive after one of the deeper blockships, or a solid choice for colder days when you want a little less deco. Visibility here can vary, but on a good day, the light filtering down onto the green-brown metal is really quite atmospheric.
Safety Notes
Wreck site - avoid penetration without wreck diving certification. Watch for sharp metal and entanglement hazards.
