Nanshin maru "black island wreck" - Civilian tanker - 45m - (21 to 32m)

The Nanshin Maru, often called the “Black Island Wreck,” sits upright, a civilian tanker that sank in World War II. We love this wreck because it’s not just a rusty hulk; it feels like a living museum, covered in growth. Dropping down, the bow is usually the first thing you see, pointing northeast. The deck sits around 21 metres, descending to the seabed at 32 metres, giving us plenty of depth to play with without pushing limits. Schools of yellowstripe cardinalfish shimmer around the mast, and we’ve often spotted honeycomb filefish blending perfectly with the encrusted metal. Exploring the cargo holds is a highlight; they’re open and inviting, allowing natural light to filter in, creating these incredible shafts of light through the water. Keep an eye out for blennies and gobies in the smaller crevices; they’re often overlooked but add a lot of character. We’d suggest an early morning dive here if you can swing it, before other boats arrive, when the light is softer and the resident reef sharks are sometimes still cruising past.
