  • Moulded boat hull with modular insert
    Patent number: 5787836
    Abstract: A moulded boat hull is disclosed which includes a modular liner which is nested within and hermetically sealed to a hollowed moulded plastic boat hull structure. The liner includes the seamless floor section of the boat, which is supported by stiffening members within the boat hull. Substantial flexibility is achieved by permitting the use of alternative liners within the same boat hull, thereby allows customization of the boat.
