SAMBU INDAH NO. 1 - Southern Islands
Sambu Indah No. 1 is a tug vessel that went down in 1988 after a collision, settling on its side at 29 metres. It's a proper old-school wreck dive for Singapore, a bit silty but with a fair amount of structure still intact for exploration. You can often see schooling batfish hanging around the main superstructure, and we’ve spotted good-sized groupers tucked into the crevices. Currents here can pick up, so it's one for those comfortable with a bit of a drift, but it’s definitely a worthwhile dive if you're keen on seeing a proper piece of history underwater.
