Abstract : The patent relates to a device whereby the underside of a semisubmerged ship or catamaran-type vessel's platform is protected from the slamming loads created by impacting waves. Elongate flexible chambers are fashioned from a flexible fabric and are arranged in a side-by-side relationship on the platform's bottom. The flexible chambers first resiliently absorb the forces of the impacting waves and then translate these forces into tensile stresses borne by interposed, rigid, structural members. The flexible fabric chambers and rigid structural members do not overly load the platform yet do provide a higher degree of protection for the platform.
