Why dive here
With 176+ marine species recorded in the area - including blue sharks, dolphins, dwarf minke whales, humpback whales and ocean sunfish (mola mola) - OIEKAST offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The Oiekast is one of those deeper wrecks that really rewards the effort. Dropping down, the silence starts to feel heavier at 40 metres, and then the dark shape of the steamship emerges from the gloom. She’s remarkably intact for a vessel torpedoed in 1917, sitting upright at 54 metres. We love finning along her deck, imagining the chaos of that December day. The bow section is particularly good, often draped in dead man’s fingers, and we've spotted conger eels tucked into every dark crevice. Our favourite detail is the stern, where you can still make out the propeller shaft, now home to clouds of jewel anemones. It’s a dive for experienced wreck enthusiasts comfortable with depth and colder water; the visibility can be variable, but on a good day, the Oiekast offers a real journey back in time, with the added bonus of some impressive Cornish marine life making themselves at home. Keep an eye on the tides for the slack window, that's key here.
