HMS SARGASSO

The HMS Sargasso, or what’s left of her, lies deep off the Cornish coast. We think it’s a brilliant dive, sitting at 38 metres on a silty seabed. She started life as a luxury yacht, the Atlantis, before being requisitioned as a minelayer in the war. You can still feel a bit of that grand past in her bones, even though she’s well broken now. We love dropping onto the bow, finding the anchor chain snaking down into the gloom. Visibility here can be tricky, so pick your day carefully, ideally on a slack tide after a spell of calm weather. Our favourite bit is exploring the engine room – it’s a proper squeeze, but worth it to see the impressive machinery. Look out for the resident conger eels, they’re huge and seem to be everywhere. You’ll also spot plenty of plumose anemones, their feathery heads swaying in the gentle current, and the occasional inquisitive bib darting in and out of the wreckage. It’s a dive for those who appreciate history and don't mind a bit of a challenge.
