    StandoutExceptional marine biodiversity

    The British Sergeant, a tanker sunk in 1942, sits upright at 20 metres, making it a truly approachable wreck dive for most recreational divers. We love the feeling of swimming into its vast cargo holds, the light filtering in through bomb holes, illuminating huge schools of glassfish that shimmer like liquid silver. It's an imposing structure, remarkably intact, with the stern section still clearly defined, and the bow pointing out into the blue. What makes it a standout for us isn't just the history, though imagining those wartime moments adds a layer of depth; it’s the sheer volume of life that has claimed it. Look out for enormous groupers lurking in the shadows and giant moray eels peeking from every crevice. We’d suggest getting there early to avoid any potential surface chop and to have the wreck largely to yourself. The visibility here can be superb, giving you long sight lines down the deck, past the corroded davits, and towards the impressive propeller. It's a proper wreck experience, full of atmosphere and fish.

    SS British Sergeant, a tanker built in 1922, met her end during one of the most intense naval operations in the Indian Ocean theatre of WWII. On April 9, 1942, the Imperial Japanese Navy launched a massive air raid on the British naval base at Trincomalee. The British Sergeant had just left the port when she was spotted and targeted by Japanese aircraft.

    The ship was bombed and sunk approximately five miles off Elephant Point. Fortunately, there were no casualties among her crew. Today, the British Sergeant is one of Sri Lanka's premier wreck dives. Lying upright at a depth of around 24 metres, she is remarkably intact. Divers can explore her decks, superstructure, and large cargo holds, which are now home to vast schools of fish. The wreck is a spectacular artificial reef, attracting both history buffs and underwater photographers.
