    StandoutExceptional marine biodiversity

    The HMS Oswaldian offers a real taste of history, sitting upright and surprisingly intact in just ten metres of water. We love a shallow wreck, especially when it’s this complete. You can trace the trawler’s lines, nose around the bow where a chain locker gapes open, and explore right back to the stern. While her superstructure is long gone, the hull is a busy apartment block for plumose anemones, their feathery tentacles swaying in the gentle surge. Look for squat lobsters tucked into every nook and cranny, and fat conger eels peering from deeper recesses. It’s a perfect site for newer wreck divers or those wanting a relaxed second dive, especially on a sunny day when the light penetrates right to the seabed, illuminating the rust and the vibrant life. We’d suggest hitting it around slack water for the best visibility; the current can kick up a bit of a silty cloud otherwise.
