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) - WAR HELMET offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The War Helmet is one of our favourite Cornwall wrecks, a proper deep dive that still offers plenty to see. She went down in 1918, torpedoed by a German U-boat, and now rests upright on the seabed at 27 metres. You descend into a green gloom that clears around 15 metres, revealing her huge silhouette. The sheer scale is what gets you first; this was a big ship, 135 metres long, and you feel that bulk as you fin along her decks. What we love here are the details. Her twin boilers are still prominent, often swarming with pollack, and you can poke around the remains of the triple-expansion engines. Look for conger eels tucked into the darker recesses, their heads peering out, wary but curious. We've seen dogfish nosing around the debris field, too. It’s a proper historical dive, a poignant reminder of WWI, and suits experienced divers comfortable with deeper, darker conditions. Visibility can be patchy, but on a good day, when that green light penetrates, it's really something special. We always suggest diving on a neap tide for the best conditions.
