    StandoutExceptional marine biodiversity

    Hooness is one of those wrecks that really sticks with you. She went down in heavy seas in '74, a motor vessel of 33.5 meters, now sitting upright at 48 meters. The depth puts her firmly in technical territory, but the reward is a remarkably intact wreck. We’ve found the stern deckhouse to be a particular highlight, often swarming with pollack. Dropping down, the first thing you notice is the way the light filters, even at this depth, catching the kelp that dances above the main deck. Penetrating the cargo holds offers a real sense of her working life, and we’ve spotted conger eels tucked into the darker corners, their heads peeking out. This isn’t a colourful reef dive; it’s a dive into history, a quiet, contemplative experience that suits divers comfortable with colder water and the challenges of deeper decompression. We’d suggest keeping an eye on the current here; it can pick up, making the descent and ascent a bit more of a workout.
