ANGSA 3 - Southern Islands

Angsa 3 isn't just a wreck; it's a slice of history, well, a dangerous slice. We love how this site feels like an archaeological dig rather than just another dive. Maxing out at 10m, it's a shallow dive, but don't let that fool you into thinking it's easy. We've seen some pretty strong currents here, so pick your day carefully, ideally on a slack tide. The wreck itself is quite broken up, but that’s part of its charm. You’re not exploring a pristine ship, more a field of intriguing debris. Look for the large, corroded boiler – that's often our favourite spot. Schools of yellowtail scad dart through the metalwork, and we often spot cuttlefish camouflaged against the rust. It’s a site that rewards patience, allowing you to really pick through the pieces and imagine the ship's past. This is a site for divers who appreciate history, enjoy a bit of a challenge, and love the hunt for macro life amongst the ruins.

Wreck History - ANGSA 3

Vessel Type
tugboat
Cause
unknown

Resting in the shallows off Singapore's Southern Islands, the ANGSA 3 is a tugboat that has been officially classified as a dangerous wreck, making it a dive for the curious and cautious. Little is known about the circumstances of its sinking, but it was declared a hazard to navigation by maritime authorities in 2007. At only 10 meters deep, the site is highly accessible, but divers should be aware of potential entanglement hazards like fishing nets and sharp, deteriorating metal structures. In the typically low-visibility waters of the Singapore Strait, the wreck emerges as a shadowy form, now providing a habitat for a variety of local marine life, including nudibranchs, gobies, and schooling fish that have made its corroded hull their home.
