Naval Applications of Composites Marine Composites specifications have been completed since 1980. Willard uses conventional construction methods: mostly hand lay-up of solid or sandwich laminates (according to contract specs) with some impregnator use. Their efficient use of a 50,000 square-foot facility and close management of production (100 boats per year) contributes to the longevity of this firm. They have also built private power and sail yachts, a 125-foot research vessel and now market a commercial version of their 18, 22 and 24 footRigid Inflatable Boat (RIB). Figure 1-27 shows a typical military boat produced by Willard. U.S. Navy warships were threatened in 1988 during the Iranian Persian Gulf conflict by small, fast Iranian Revolutionary Guard gunboats. After capturing one, the Navy began using it for exercises off San Diego and became impressed with the capabilities of this size vessel. Recognizing the cost effectiveness of this type of vessel and the range of mission capabilities, procurement of tthis type of craft for operation with Special Boat Units started. Figure 1- 28 shows a typical fast patrol boat design, this one from McDonnell Douglas and Magnum Marine. The U.S. is slightly behind its European counterparts in the exploitation of these types of vessels in support of naval operations. Many countries have opted not to develop navies based on ships with offshore capabilities and instead rely on fast, heavily armed patrol craft. Fast patrol boats around 100 feet in length, like the one shown in Figure 1-29, offer increased capability and endurance over the smaller cigarette type vessels.
