Later they were put into position on the Calahan bank by the USS Gear and sunk to provide a breakwater at the mouth of Apra Harbor. Depth to the top is 40’/13 meters. Depth to the main deck is 60/20 meters and the ship has a list to the right (starboard side).

remo032 - 4/11/2014 12:15 PM Rating Added: 4 A very easy wreck dive. It’s large and easy to ID all the different parts of the barge along with a lot of smaller top structures that are easy to explore inside since they have two open doors and are only about the size of a small living room.
