Heian Maru
The largest wreck in the lagoon: a 1930 NYK liner (11,614 t, 510 ft) converted to a submarine tender, set on fire by carrier aircraft on 16 Feb 1944 and sunk on 17 Feb. She lies on her port side with the hull starting at about 10–12 m; the holds contain torpedoes, shells, submarine parts, china and bottles, and the huge screws are a highlight.
depth: 10–35 m
