Abstract : Tough lightweight fiber systems combined with preform framing are allowing for new innovations in durable lightweight boat structures for US Navy Combatant Craft. Designs utilizing this new technology offer weight savings potential of 40% to 60% when compared to conventional construction. Structural weight savings and shock mitigation have been demonstrated by combining lightweight membrane hull laminate and suspended cockpits. The single skin membrane structure reduces weight and absorbs wave impact energy though panel deflection. The suspended cockpit further mitigates shock due to wave impact as the deck is allowed to move relative to the hull. The project also provides for research into the effects of pressurizing the hull to deck cavity. The results of two demonstration craft, 8.5 m and 11 m are presented in this paper.
