ABSTRACT:
A catamaran type vessel has two parallel hulls and a metal tubular framework linking the hulls. Rigid members extend longitudinally within the hulls and have extensions projecting from the upper surfaces of the hulls for coupling with the framework. This reduces hull stresses and allows lighter hulls. Expanded plastics foam may be used to hold the rigid members in the hulls. The hulls may be inclined inwardly to give an asymmetrical catamaran type configuration.
