The last operational fast patrol boats built for the RN, these had welded aluminium frames, a double mahogany skin and fiberglass sheathing below the waterline. A feature of the design was the great beam to accommodate the three engines, which with the hydraulic flap in the transom helped to maintain the trim.
Although the requirement for FPBs had officially lapsed with the demise of Coastal Forces they played a useful role as targets and in fishery patrol duties. They were originally intended to have the 84mm CFS-2 (Coastal Forces System Mk 2) stabilized gun system, an adaptation of the Centurion tank's 20pdr. The prototype tested in Bold Pioneer had many teething troubles and when Coastal Forces were axed the development was not pursued. Although originally intended to have four TT they were given side-launching cradles to save weight.
