A review is made of existing marine applications of fiber- reinforced composites. Problems arising in the design of marine-type composite structures, including evaluation and selection of materials, structural analysis, buckling behavior and performance of connections, are discussed with particular reference to large, high-performance GRP hulls. Suggestions are made on items of research and development needed in this field. The greatest scope for increased application of fiber-reinforced composites in the marine field appears to lie in construction of medium-size hulls in the 20 to 40 m range, including particularly fishing boats, together possibly with large patrol boats and service vessels for the offshore gas/oil industry. While design studies for larger ships have indicated that GRP tankers, trawlers and ferries of up to 80 m might prove economically viable, present cost figures suggest that GRP is unlikely to compete with welded steel construction in ships of over 50 m unless a special requirement arises, eg for carriage of corrosive cargo or, in the case of minesweepers, for a non-magnetic hull.
