    StandoutExceptional marine biodiversity

    Ah Lam II is one of our favourites in the Southern Islands, definitely a standout. It's a tugboat that went down back in '92, and the story of its sinking – squeezed between a bulk carrier and its own tow – gives it a real character. Dropping to 27 metres, you'll find the wreck largely intact, sitting upright on the seabed. We love exploring the engine room, often finding large groupers lurking in the shadows. The wheelhouse is usually teeming with schooling fusiliers, so thick they almost block out the ambient light, and we've regularly seen barracuda circling the mast. It's a surprisingly fishy wreck, probably because it's one of the more substantial structures down there. For photographers, the way the light filters through the superstructure can be beautiful on a sunny day, especially around mid-morning. We'd suggest checking the tides; a slack tide makes for a much more relaxed exploration, though a gentle current often brings in more pelagics. Visibility here can be hit or miss, typical for Singapore, but when it's good, Ah Lam II really shines. It's an excellent dive for those who enjoy wreck penetration or just want to spend time observing the resident marine life.

    AH LAM II Wreck History

    Cause

    collision

    The sinking of the tugboat "AH LAM II" was a sudden and violent event in the bustling shipping lanes around Singapore. On January 28, 1992, the tug was towing the barge 'PU 1804' when the massive bulk carrier 'Bonito' made the dangerous decision to pass between the tug and its tow. This maneuver likely caused the towline to snap or foul, tripping the much smaller tug and capsizing it almost instantly, sending it to the seabed in one of the world's busiest maritime crossroads.

    Today, the "AH LAM II" lies at a depth of 27 meters near Singapore's Southern Islands, offering a fascinating dive for advanced-certified divers. The visibility in this area can be challenging, which adds to the atmosphere and sense of discovery when the wreck emerges into view. The tug sits upright and is largely intact, providing a compact but compelling site to explore. It is now home to a variety of marine life, including soft corals, nudibranchs, and schooling fish, a poignant yet beautiful memorial to a maritime tragedy.
