USCG long range interceptor using the stern launching ramp of the USCGC Bertholf -- a frigate sized cutter.
The stern launching ramp is a technology that allows patrol vessels to launch and retrieve smaller boats without requiring the mother vessel to come to a halt.[1][2] Boats propelled by high-powered water-jets can drive themselves back on board their mother vessel's ramp, even when their mother vessel is traveling at noteworthy speed.
Some modern patrol vessels are equipped with a stern launching ramp, for deploying smaller rescue or pursuit boats without requiring the parent ship to first come to a halt.[1][3] Typically the smaller craft are powered by water-jets, and can drive themselves up the ramp by their own power.
The stern launching ramps on the United States Coast Guard's Marine Protector cutters require only a single crewmember to remain on deck when its short range prosecutor boat is deployed or retrieved.[4]
When the brand new USCGC John F. McCormick visited Astoria, Oregon, the station of its namesake John F. McCormick, Jeff Heffernan, of the Daily Astorian described how a stern launching ramp allowed a parent vessel to launch her boat in larger swells.[5]
