About this site
The San Francisco Maru, called the Million Dollar Wreck, is a 385-foot (117 m) Japanese cargo ship in Truk Lagoon, resting at about 60 metres (160 to 210 feet). It is a deep wreck for experienced divers, in silty conditions.
The holds still hold military cargo in good condition, including tanks, trucks, mines, aircraft bombs and parts of fighter aircraft. The deck, with its large tanks and vehicles, is covered in soft corals and sponges. Divers with penetration experience can enter the engine room, a dark labyrinth of machinery.
Because of the depth the wreck sees fewer divers. Schools of jacks and barracuda circle it, and the occasional reef shark passes.
