Abstract
A deep-drawn, marine hull having a sandwich structure and watercraft utilizing same are provided. The hull includes an outer skin having a waterproof outer surface, an inner skin having a compartment-defining outer surface and a shock absorbing, cellular core positioned between the skins. The skins are bonded to the core by press molding. The cellular core has a 2-D array of cells, each of the cells having an axis substantially perpendicular to the outer surfaces. Thickness of side walls of the hull is substantially uniform to maximize stiffness of the hull. The cells absorb energy of an impact at the outer surface of the outer skin by deformably crushing. Air trapped within cells which are not completely crushed or punctured by the impact provide the hull with buoyancy to allow the hull to float at the surface of a body of water.
