Moulded boat hull with modular insert

A moulded boat including first and second members:

• said first member being an integrally moulded plastic boat hull structure comprising opposing inner and outer shells which are integrally joined around peripheral portions thereof and which are also integrally joined at adjacent regions within said periphery by a plurality of horizontally spaced and longitudinally extending stiffening members, integrally joined to and extending between said inner shell and outer shell, to establish a generally hollow volume hull, with said stiffening members recessed within the hollow volume and projecting upwardly towards the open region of the hollow volume;
• said second member being an integrally formed liner, nested within the hollow volume of said hull, said liner including a generally vertical wall extending downwardly along at least a portion of the periphery of said liner and a generally horizontally extending bottom wall spanning between opposed lower edges of the peripheral vertical wall;
• said bottom wall having opposed inner and outer surfaces, said inner surface abutting at least a portion of generally horizontally extending surfaces at the terminus of said hull stiffening members, with said hull stiffening members operatively supporting said bottom wall;
• and
• securement means for fixedly securing said liner to said hull to provide a unitary boat structure.
