Artifact Condition:	The lighterage is made up of a series of steel rectangular cells connected together. It is 18 rows long and 6 sections wide. There is a long open access port near one corner. A few of the cells have broken loose, most likely from impact with the seabed. Some of the cells have holes in them. There are a couple tires and some mangled siding lying about.

Additional Information:	There were 5 types of P-Series pontoons in various shapes for use in 7 different barge or causeway configurations. The 18 x 6 type barge is the 2nd largest and is made up of P-1 cubicle shaped pontoons which were the most common type. They were 5' x 7' x 5' and 3/16" thick. Propulsion could be added making a lighter that was capable of up to 250 tons or accessories could be added to convert it to a 1500 barrel capacity fuel storage barge. Add hinges and it could be a wharf for outfitting or repair. They were first developed in WW II and used through Korea & Viet Nam. It is being used extensively as a habitat by fish and eels.
