BOYNE - Cornwall & Devon

The Boyne, a barque that ran aground in Mullion Cove back in 1873, offers a different kind of dive. With a maximum depth of just 2 metres, it’s really more of a snorkel or a very shallow shore entry, ideal for easing back into things or for newer divers getting comfortable with wreckage. What you’ll find is a scattered array of timbers and hull sections, well-worn by the waves over the last century and a half. It’s not about penetration here, but about exploring the nooks and crannies of the exposed remains. We’ve spotted plenty of blennies darting between the timbers and anemones clinging to the darker recesses, a testament to how life reclaims even the most broken things. It’s a good spot for a relaxed look around, particularly on a calm day when the water clarity lets you really pick out the details.
