Both boats a top speed of over 40 knots (74 km/h; 46 mph) from the four 2,500-horsepower (1,900 kW) Packard W-100 gasoline engines with shafts. PTF-1 and PTF-2 were armed with two Bofors 40 mm guns , two twin 20-millimeter (0.79 in) cannon , one .50-caliber machine gun , one "Piggyback" 81 mm mortar and one smoke generator .
The first Uniflite boat an all fiberglass 17' outboard. Uniflite soon added a 14', an 18' and a 20' outboard and inboard/outboard boats, followed by a 25' express cruiser followed by a 31' and a 34' boat. Uniflite was the only boat builder exclusively using fire-retardant resins in the production of pleasure boats. [citation needed]

The German Water Police rented a Combat Boat 90H from the manufacturer Dockstavarvet for the 33rd G8 summit in Heiligendamm, Germany. This boat was involved in a high-speed chase with three Greenpeace RIBs who were trying to enter the restricted area near the hotel where the meeting was being held. A video clip of the incident was later widely ...
The vessel is equipped with eight, 20-cylinder (20V32/44CR) MAN 11,200 kW diesel generators providing a total installed power of 95 MW, driving 12 Rolls-Royce azimuth thrusters which provide dynamic positioning (DP3) and propulsion. The vessel's maximum speed is 14 knots (26 km/h; 16 mph).
An engine order telegraph or E.O.T., also referred to as a Chadburn, [1] is a communications device used on a ship (or submarine) for the pilot on the bridge to order engineers in the engine room to power the vessel at a certain desired speed.
The Sea Sled is a direct forerunner of the modern high speed catamaran or tunnel hull. The reduced friction is due to a "trapped" gas film between the hull surface and water. A similar effect is seen in super-cavitating torpedoes where a gas generator creates a film separation to water friction.
