    StandoutExceptional marine biodiversity

    The U 153 is a bit of a mystery, lying at 57 metres, scuttled in 1921. We love dives like this, where the history feels palpable. Dropping down, the visibility in this part of the Channel can be a lottery, but when it’s good, the sheer scale of the U-boat emerges from the gloom. At 64.9 metres long, she’s an imposing sight. You’re really here for the wreck itself. She sits relatively intact, a shadowy leviathan, and you can still make out the conning tower and the torpedo tubes if you know where to look. It’s a deep penetration dive for experienced wreck enthusiasts. The light fades quickly at this depth, so torches are essential to pick out the details and the marine life. Conger eels have made the internal structure their home, peering out from open hatches, and the hull is covered in those vibrant jewel anemones that thrive in the deeper, darker water. It’s a serious dive, demanding good gas planning and solid deep diving skills, but the rewards are a proper piece of history.
