MERSING - Southern Islands

We’re going to be straight with you: Mersing isn't a deep dive, nor is it going to blow your mind with massive pelagics. But if you’re into Singapore’s lesser-known history and like a wreck you can really get to grips with, this is our pick. The wreck lies in shallow water, around 8 meters, which means plenty of ambient light filtering through the green hue. You can spend a good chunk of time exploring the skeletal remains of this old cargo vessel. We love how the structure has become a home for so many critters: look closely and you’ll find nudibranchs crawling along the plates, small schools of fusiliers darting through the rusted holds, and often a grumpy stonefish or two camouflaged on the deck. It’s a great site for newer wreck divers or photographers wanting to practice their skills without the pressure of depth or strong currents. Just watch out for fishing lines, a common sight around Singapore's wrecks.
