Composites frequently referred to as fiberglass or FRP are usually thought of as the material of choice for recreational boats. Recently though, composites have been used for 57.3 m (188 ft) minehunters and a 49 m (161 ft) yacht. Ten years ago these FRP vessels would have been at the upper limits of perceived size limitations, but practical limitations on the size of vessels using composites as the primary structural material are premature due to continuing advances in the materials and processing technology. Composites are used for small sections of large steel vessels including non-pressure hull decking for submarines, weapons enclosures for destroyers, and funnels on cruise ships. Potential uses on large cargo vessels include bulbous bows, hatch covers, stern fairings, deck machinery enclosures and non-structural interiors. This paper reviews current usage and explores future potential on the use of composites on larger vessels.
