The American Tanker is a large concrete barge that was used during World War II to transport war materials from the United States to Guam. It was one of five barges that were brought to Guam.
This is a great dive for those with an interest in wrecks but little or no experience diving them. It also has some opportunities for experienced wreck divers to explore more deeply.
Follow the marker buoy down and you will see the looming shape of the tanker, which has become alive with a wide variety of small coral colonies and tropical fish.
The rear deck of the tanker has one bulkhead opening to the inside of the barge machinery room. This area is very accessible and has a large opening to the upper deck. This area is used for training wreck diving students.
The pilot house, which was always manned by one seaman steering the barge as it was being towed, is very easy to enter and exit. This is a favorite place for tropical fish feeding.
There are two more small deck houses but most of this barge was used to store fuel so the openings into the lower holds, which are completely empty, are very small and a tight fit.
Most divers go to the upper shallow reef and around the coral heads and artifacts still present there.
