Y.M.S. 24 (PART OF) - Marseille & Calanques
The Y.M.S. 24, or what’s left of her, is a proper technical dive, and we rate it highly for that specific crowd. Sitting at 55 metres, this American minesweeper was lost during Operation Dragoon in 1944. What you find now is a fractured wreck, split into several pieces, which makes for a fascinating exploration. We love navigating the debris field, poking around the ribs of her hull. The sheer scale of the breaks gives it a raw, almost violent feel, a stark reminder of her demise. Visibility here can be excellent, especially outside of summer, often pushing 20 metres, making the descent into the deep blue a real treat. Keep an eye out for conger eels peering from every crevice, and big lobsters tucked into the darker corners. We often find large schools of barracuda hanging just off the wreck, silhouetted against the surface light. It’s a dive that rewards careful planning and respect for depth, ideal for experienced technical divers looking for a piece of history with a real sense of place. Expect a good current sometimes; it’s the Med, after all.
