    StandoutExceptional marine biodiversity

    The Poussoir is a fantastic wreck if you enjoy something a little different, and we always suggest it for divers who appreciate history alongside a good dive. She’s a tug, and a French one at that, which went down in 1918 after a collision. You’ll find her upright on the seabed at 20 metres, which is a comfortable depth for most, but the real draw is her incredible state of preservation. We love exploring the engine room, still largely intact, and poking around the stern where the propeller blades are usually visible, often draped in dead man's fingers. Because she’s been down for over a century, the Poussoir has become a proper artificial reef. The metalwork is completely encrusted with jewel anemones, often a brilliant orange, and you’ll spot plenty of wrasse darting in and out of the crevices. We’ve seen conger eels coiled up in the darker sections more times than we can count. Visibility can be hit or miss in the English Channel, so we’d suggest aiming for slack water around neap tides; it really makes a difference to the colours and overall experience. It’s a genuinely engaging dive for anyone comfortable with wreck penetration, offering a real sense of stepping back in time.
