Cutter Boat – Over the Horizon
The Cutter Boat – Over the Horizon (CB-OTH), is a cutter-deployed rigid-hulled inflatable boat in service with the United States Coast Guard. It is designed to pursue and interdict fast, non-compliant vessels. As of March 2018, 78 boats have been delivered, and deployed on a variety of cutters, including the Maritime Security Cutters, Hamilton-class High Endurance Cutters, and Famous and Reliance-class Medium Endurance Cutters, and the Sentinel-class cutters.[1] Eventually, at least 101 boats will be deployed.[2]
Design
[edit]The Over the Horizon boat is 24.75 feet (7.54 m) in length. Its fourth generation is manufactured by SAFE Boats International of Port Orchard, Washington. It is part of a 101-boat order worth up to $58.9 million. The hull is fabricated 5086 marine grade aluminum and it has a 22-inch-diameter (560 mm) foam collar. It is an inboard/outboard design powered by a 500 hp (370 kW) Cummins diesel inboard engine with a Hamilton jet drive.[3][4]
The boats are equipped with radar, electronic compass, GPS, and other electronic navigation systems, loud-hailer, and both HF and VHF-FM radios.[3] The boats come equipped with five special shock-absorbing seats, necessary because proceeding at high speed, over waves, could injure crewmember's spines.
A version of the boat with an all-black sponson and forward machine gun mount is used by Maritime Safety and Security Teams and the Maritime Security Response Team.
Use
[edit]The Coast Guard's newer cutters, the National Security Cutter, Sentinel-class cutter, and the smaller Marine Protector-class cutter are designed with a stern launching ramp. Stern launching ramps permit the cutters to deploy and retrieve water-jet propelled boats, without first coming to a stop. The Marine Protector-class cutters require just a single crew member to remain on deck to control the deployment and retrieval of its jet boat.
