GRESABIL - Southern Islands
Gresabil isn’t one of Singapore’s prettiest dives, but it’s definitely one of our favourites for a good reason. This old tug, sunk way back in ‘71, sits upright at 30 metres. It’s a proper wreck, still holding its shape, with a real sense of history. We’ve had some fantastic dives here, especially when the current picks up and you get that drift feeling along the deck. The visibility can be a bit hit or miss, typical for Singapore, but on a good day, you can make out the entire profile of the vessel. We love poking around the wheelhouse area, which is pretty intact, and the engine room. You'll find batfish often schooling around the mast, and we’ve seen some surprisingly large groupers lurking in the shadows. It’s an ideal spot for anyone who enjoys wreck penetration, as long as you're comfortable with limited light and tight spaces.
