    StandoutExceptional marine biodiversity

    The Kathleen is a proper old-school wreck dive, and we love it for that. She was a fishing vessel that went down back in '75 after hitting something off Jersey. Now, she rests upright at 23 metres, a fantastic canvas for cold-water marine life. You’ll find her largely intact, a real pleasure to navigate. We always head for the wheelhouse first; it’s still pretty recognisable, and you can almost imagine the skipper at the helm. The bow section is our favourite though, often draped in dead man's fingers and home to some hefty conger eels peeking out from every crevice. Look out for the resident pollock darting through the superstructure. Visibility can be a bit hit or miss, typical for the UK, but on a good day, the light filtering through the water and illuminating the orange and white anemones is just stunning. It’s a dive that rewards a slow pace and a good torch, perfect for photographers or anyone who appreciates a bit of maritime history.
