    StandoutExceptional marine biodiversity

    Merrbar, a small fishing vessel that went down in 1988, is a cracker of a dive if you're looking for something a bit different off the Cornish coast. We love a good small wreck, and this one, at only 7.6 metres, is easily taken in on a single dive. She sits upright in 33 metres, and while the structure itself is starting to break down, the way the current has sculpted the metal is pretty fascinating. What makes Merrbar really shine for us is the sheer volume of life that has claimed her. You'll find the entire wreck draped in plumose anemones, their white tentacles swaying like a field of flowers in the surge. Look closer amongst the tangled fishing gear and you’ll spot velvet crabs scuttling, and often a squat lobster or two peering out from a crevice. It’s a photographer's dream on a clear day, especially when the light shafts through the kelp forest that has grown up around her. It’s a dive that rewards slow exploration, perfect for those who enjoy picking out the smaller details and don't need a massive freighter to feel like they’ve had a proper wreck dive.
