Dive-site story
Sunk during the early stages of the Pacific War off the Sarawak coastline, the armed Japanese transport ship Katori Maru rests in several fractured sections on a sandy seabed. Decades submerged have transformed the twisted iron hull into a dense artificial reef draped in soft corals, sponges, and expansive gorgonian fans. Visibility fluctuates with coastal tides and sediment, making spatial awareness and careful buoyancy essential as you track the hull profile.

Massive aggregations of pelagics and schooling fish patrolling the superstructure
