    StandoutExceptional marine biodiversity

    This isn't just another fishing vessel on the seabed, it’s a properly moody wreck. Dropping down onto Les Mercenaires, you immediately feel the weight of its story. She lies mostly intact at 30 metres, an upright hull, listing slightly to port, with the wheelhouse still largely discernible. We love poking around the stern, where the nets are still eerily draped, giving you a real sense of its working life before it went down. For those who appreciate maritime history with their dive, this is a real treat. We’ve found conger eels tucked into every dark corner, their heads poking out like grumpy old men, and the odd inquisitive pollack will often shadow you. Visibility here can be hit or miss, typical for the English Channel, so we always suggest picking a day with settled weather and slack tides. Catch it right, and the light filtering through the green water makes for some dramatic photo opportunities. It's a proper British wreck dive; a bit chilly, a bit silty, but utterly rewarding.
