The Defender class boat, also called Response Boat - Small (RB-S) and Response Boat - Homeland Security (RB-HS), is a standard boat introduced by the United States Coast Guard in 2002. The boats serves a variety of missions, including search and rescue, port security and law enforcement duties and replaces a variety of smaller non-standard boats.
The design length of the hull is 25 feet and the boat is officially referred to as such. However, the overall length with engines mounted is approximately 29 feet (8.8 m). Powered by twin 225 hp (168 kW) outboard motors, they are capable of speeds excess of 46 knots (85 km/h) and have a range of 150 to 175 nautical miles (324 km), depending on the class. The boat requires a minimum crew of two persons, but has a carrying capacity for 10 persons. The boat is easily trailerable and can be transported by a C-130 Hercules aircraft or truck.
Although superficially similar to a rigid-hulled inflatable boat, the Defender is actually an aluminum-hulled vessel, equipped with a hard foam-filled floatation collar. The boats are built by SAFE Boats International (Secure All-around Flotation Equipped) of Port Orchard, Washington, a vendor of government and law enforcement boats.

Design

The Defender class utilizes a rigid deep-V hull constructed of marine grade aluminum. While similar in appearance to the sponson of a rigid-hulled inflatable boat the Defender's collar is actually made from rigid polyethylene foam. The boat is powered by two 225 horsepower (168 kW) outboard engines, usually Honda four-strokes though Mercury engines have also been used. Tow bitts are fitted forward and aft which also serve as mounting points for M240B or M60 machine guns. Variants

The Defender A Class or Response Boat - Homeland Security (RB-HS) was the first version of the Defender Class and entered service in 2002. Some A Class boats in service with the Maritime Security Response Team (MSRT) have gray collars instead of the more common orange.

B Class

The Defender B Class, also known as the Response Boat - Small (RB-S) is a further development of the A Class. First entering service in 2003 it has a slightly longer cabin, additional spotter windows aft, shock mitigating cabin seats, a smaller 105 gallon fuel tank, and various other minor changes. It is the most common of the three classes.

C Class

The Defender C Class, sometimes know as the Response Boat Small - Charlie, is a modification of the B Class and was designed as a replacement for the aging 25-foot (7.6 m) Transportable Port Security Boats (TPSB) currently used by Port Security Units. The C Class has a gray foam collar, a cabin climate control system, and an increased armament of one M2HB .50-caliber machine gun on a modified forward mount and two M240B machine guns on port and starboard mounts just aft of the cabin. The first C Class boats were delivered to Port Security Unit 305 in May 2008 for testing and entered operational service at Naval Station Guantanamo Bay, Cuba in 2009.
