MANDIRI I - Southern Islands

Mandiri I is our pick for a decent wreck dive when you’re in Singapore. This tug sank in a storm back in ‘91, heading from Palembang to Batam. Now she sits upright on the seabed at 20 metres. We love dropping down and seeing her emerge from the green haze, usually with a decent current pushing you along her hull. There’s a real sense of history here, a proper wreck with a story. You can usually make out the wheelhouse, the superstructure, and the main deck area, all encrusted now with sponges and hydroids. The wreck itself isn't massive, but it’s large enough to offer plenty of nooks and crannies for exploration. Look for schools of yellowtail scad flitting around the mast, and we’ve often spotted barracuda patrolling the deck. Keep an eye out for resident groupers peering from shadowy openings. Visibility can be hit or miss, typical for Singapore, so choose your day. Go on a slack tide for the best chance to really take your time and appreciate the Mandiri I’s character.
