    StandoutExceptional marine biodiversity

    The Essonite, or what we strongly suspect is the Essonite, is a proper technical dive, sitting deep at 56 metres. This isn't one for a quick splash, but if you're comfortable with the depth and the chill, it delivers a powerful experience. When we've dropped down, the sheer scale of the tanker feels immense, even at 53 metres long. You'll find yourself drifting over plating draped in dead man’s fingers and anemones, with conger eels peering from every dark recess. We've seen ling nosing around the collapsed sections, and if you’re lucky, a curious dogfish might glide past. The wreck’s character is defined by its history; torpedoed in 1917, you can almost feel the weight of its story. It’s a somber, silent place, best for experienced tech divers who appreciate a quiet, historical encounter rather than a colourful reef. Pick a day with minimal surge and aim for slack tide; otherwise, it’s a challenging drift.
