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) - HMS Bulwark offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
Now, the HMS Bulwark. This isn't your pretty reef dive, it’s a proper piece of history, sunk by internal explosion during WWI. We love it because it’s a big, broken monster of a wreck, scattered across the seabed near Sheerness. You drop down, and the scale of the destruction hits you immediately. We’re talking about massive plates of steel, twisted like paper, and huge sections of the hull lying on their side. Visibility can be a bit 'Cornwall', so we always aim for slack water on a decent tide to get the best out of it. There are often big conger eels tucked into the darker corners, and crabs scuttling over the debris. It’s a dive for those who appreciate the sheer power of a wreck, the engineering, and the quiet, almost eerie atmosphere of a battleship that met such a violent end. Our favourite part? Finding one of the enormous steam engines, still largely intact, a testament to the sheer scale of these old warships. Bring a good torch; there are plenty of nooks and crannies to peer into.
