Rudderless river boats advance Navy test program
Tr P B R patrol boat with riverine propulsion is a forerunner in a new military concept. Two or three boats completed have run tests in Bellingham Bay Washington, reaching speeds over 25 knots and ejecting 4600 gallons of water per minute. Built from resin reinforced fiberglass and powered by two 220 horsepower diesels, the craft carries two .50 cal and one .30 cal machine guns. 120 units have left United Boatbuilders with 40 more to complete under Navy contract. Potential missions include troop delivery or counter guerrilla actions.
