American Tanker
A 300+ ft (about 90 m) concrete tanker barge sunk at the mouth of Apra Harbor; the hull lists to starboard with the pilothouse at about 13 m and the main deck at about 20 m. Sources give maximum depths between about 27 m and 34 m. A boat dive for all levels outside the hull; going inside needs wreck training.
depth: 13–27 m
