W H DWYER - Cornwall & Devon

The W H Dwyer, lying at a respectable 52 meters, is a proper technical dive, and one we genuinely love for its intact structure. Drop down onto her and you’ll find the steamship sitting upright on the seabed, her bow pointing north. We usually start our exploration around the stern, where the triple expansion engine and two boilers are still very much in evidence. The swim-throughs here are exhilarating, but only for those with the right training and comfort level. What really makes the Dwyer stand out for us isn't just her size, but the way marine life has completely taken over. Enormous conger eels peer out from every dark nook, and we’ve seen some truly massive pollack circling the superstructure. Visibility can be a bit of a gamble in the English Channel, but when it's good, seeing the full length of her loom out of the green is spectacular. Our tip? Aim for slack water, always, and be prepared for a decent deco obligation. This isn't a site for the uninitiated, but for seasoned wreck divers, she’s a gem.
