Hirokawa Maru (Bonegi I)
Bonegi Wrecks · Solomon Islands
Japanese transport beached on 14 November 1942 during the naval battle of Guadalcanal, then bombed and burned out by US aircraft. The 156 m hull lies on her port side perpendicular to Bonegi Beach, with the bow in 5 m of water and the stern dropping to about 55 m — divable as a shore entry shallow swim or as a deep technical descent into the holds and engine room. Hard corals, gorgonians and brain coral now sheathe the steel; sweetlips, batfish, lionfish, fusiliers and moray eels patrol the wreckage and cleaning stations along the upper deck.
