The "American Tanker" is actually a large 300+ ft concrete barge. In late 1944 the barges were loaded in Honolulu with war supplies, and then towed to Guam from Honolulu by the USS Bannock and Arikara. 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).

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.
