GUYONA - Cornwall & Devon

The *Guyona*, a compact fishing vessel resting at 51 metres, is one of our favourite deep wrecks off the Cornish coast. Dropping down, you hit the bow first, often with a bit of a current pushing you along the deck. The wheelhouse is still intact, though a bit squashed, and it’s always interesting to peek inside, imagining the last moments. What we really love about the *Guyona* is how quickly it’s become home to so much life. You'll find good-sized conger eels tucked into any available hole, and often a decent number of lobsters marching across the deck. Keep an eye out for dogfish resting on the sand nearby too. Visibility can be a real lottery out here; we've had days of 20 metres and others where it's a murky five. Best to go on a slack tide, otherwise, you're looking at a serious workout. This isn't a wreck for beginners; the depth and potential for current mean you need your wits about you, but for experienced tech divers, it’s a rewarding dive.
