Shinwa Maru
Why dive here
With 84+ marine species recorded in the area - including whale sharks and mantis shrimp - Shinwa Maru offers some of Cenderawasih Bay's richest diving. Water ranges 27-31°C, warmest January, March, December.
The Shinwa Maru, a 120m Japanese transport, sits upright off Marsinam Island, deep in Cenderawasih Bay. It’s a wreck that demands respect, extending well beyond recreational limits, down to 120m. We typically hit the shallower sections, finding the bridge and cargo holds still remarkably intact. Look for the bow gun and the general ship structure, now a home for schooling fusiliers and the occasional grouper. This site is definitely one for advanced wreck enthusiasts comfortable with deeper profiles and potentially strong currents.
