    StandoutExceptional marine biodiversity

    The *Sheer Grace* offers a solid, if not spectacular, dive off the Cornish coast. This 11.6m cruiser, which sank in 2004 after a fire, now rests upright at 19 metres. What remains is essentially a burned-out hull, but it’s still an interesting poke-around for newer wreck divers or those looking for a shallower second dive. We’ve seen good-sized wrasse darting in and out of the skeletal framework, and the occasional dogfish tucked away. Current can pick up here, so we’d suggest timing your dive for slack water, particularly if you want to properly explore the scattered debris field around the main hull.
