ABSTRACT 



Two plastic mooring buoys have provided good service as part of 

 moorings for the Fleet in San Diego Bay for a period of 4 years. One buoy 

 with a hand lay-up fiberglass-reinforced polyester shell is in appreciably better 

 condition than the other one with a spray-up shell of fiberglass-reinforced 

 polyester resin. A third plastic buoy with an improved design is in excellent 

 condition after 1 year of service to the Fleet in Pearl Harbor. An analysis of 

 the costs of purchasing and maintaining steel and plastic mooring buoys is 

 presented. It indicates that after the present supply of World War 1 1 mooring 

 buoys is exhausted, the Naval Facilities Engineering Command field activities 

 should use plastic mooring buoys as replacement becomes necessary.
