<p>This hull is of the type composed of two elements, an upper element (3) and a lower element (2), respectively, produced separately in reinforced heat-curable resin, joined to one another by bonding of their edges and forming a cavity lined with the expanded resin. In order to facilitate manufacture of this hull, to reduce its cost, to increase its strength and to prevent any injury to the user, its main element has, in transverse section, the shape of a recumbent C whose two turned parts (2b) disposed above the spine of the C forming the transverse lower wall of the hull are substantially in the extension of each other and are integral with curves (2c) which alone form the sides of the hull. The other element (3) has the form of a panel closing the opening (4) of the main element, being connected to the edge of the said opening. <IMAGE></p> |
