About San Francisco Maru
San Francisco Maru is one of Chuuk's signature deep wreck dives, prized for preserved wartime cargo and a long technical profile that rewards careful planning. The wreck sits deep enough that the cargo spaces, deck structure, and surrounding steel matter more than a quick sightseeing pass. It is a boat dive for experienced teams, with little lagoon current but enough depth to make gas and decompression the central planning concerns.
