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) - HMML 380 offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
We’re going to be straight with you: the HMML 380 isn't a deep dive, sitting at a maximum of 7m. What it lacks in depth, though, it more than makes up for in atmosphere and sheer historical presence. Sunk in 1919, this wreck is a tangle of metal, now softened by time and a thick coat of marine growth. Drop down and you're immediately in its world. The structure is broken, but you can still pick out the ribs and plates of the old vessel. Our favourite bits are where the light filters through gaps in the wreckage, illuminating clouds of juvenile pollock that dart in and out. Keep an eye out for dogfish tucked under larger plates, and the vibrant colours of jewel anemones clinging to every surface. It’s an ideal spot for macro photography, or for newer wreck divers wanting to experience a piece of history without the challenge of depth or strong currents. Just remember your drysuit; it’s the UK, after all.
