R M HUNTON - Cornwall & Devon

The R.M. Hunton isn’t about depth, it’s about history and how nature reclaims things. We love this site for its sheer accessibility, sitting at just 8 meters, making it a cracking dive for newer wreck enthusiasts or those looking for a relaxed bimble. What you’ll find is the scattered remains of a steamship, broken up but still very much a wreck, draped in colourful anemones and sponges. As you descend, the wreck’s iron bones emerge from the silty seabed, providing shelter for everything from inquisitive wrasse to plump lobsters tucked into crevices. We particularly enjoy exploring the engine room remains, where light filters through the structure, illuminating clouds of juvenile fish. It’s a gentle dive, usually with mild currents, which means you can really take your time examining the details, imagining the ship's final moments after striking Cockburn Rock. Our tip: go at slack water on a sunny day; the visibility improves dramatically, and the colours of the encrusting life really pop.
