Combat Rubber Raiding Craft

The F470 Combat Rubber Raiding Craft (CRRC), also known as the "Combat Rubber Reconnaissance Craft," is a specially fabricated rubber inflatable boat often used by United States Navy SEALs and Marines, among others. Though Zodiac Marine & Pool produces a large range of both inflatable and rigid-hulled boats, the name "Zodiac" has become synonymous with the CRRC in popular culture.

The boat can be used for over-the-horizon transportation, inserting lightly armed raiding parties or reconnaissance teams onto beaches, piers, offshore facilities and larger vessels. The CRRC can be inflated in minutes by foot pump, compressor or CO₂ tank and can be deployed from shore and a variety of vessels. Additionally, it can be launched from several types of aircraft and submarines equipped with a special lockout chamber or a Dry Deck Shelter. Its chief advantages are light weight, compact size when stowed, and the safety imparted by its super-buoyant nature (which gives it the ability to operate in relatively high seas) stealth, and versatility.

A total of eight individual airtight chambers comprise the F470. The main hull or gunwale contains five intercommunicating chambers, which are separated by internal baffles and valves. This means that a single leak will not result in loss of pressure throughout the boat, and that air can be bled between chambers to compensate for loss in one. Two additional chambers, located below the gunwale on either side and called "speed skags," provide cushioning for the boat's occupants and additional buoyancy in case of pressure loss in the hull. The final chamber is an inflatable keel tube which runs the length of the craft and gives the bottom of the hull a "V" shape, imparting directional stability and additional shock absorption. A wooden "transom" board at the stern provides a mounting point for the outboard engine(s). The deck (floor) is composed of four interlocking aluminum plates, which are fixed to the "thrust board" at the bow end and the transom at the stern. This rigid structure, spanning the entire internal area of the boat, prevents the hull from collapsing or "taco-ing" under power.
