Abstract
A hull structure of nonmetallic material, in particular of a reinforced plastics material, for boats, ships, minesweepers and the like includes a preferably one-piece shell (1) and at least one deck (2, 2'). A plurality of ribs (3) are distributed along the length of the hull and extend across the corresponding transverse section of the shell (1). A plurality of transverse members (4, 4') (known as beams) extend directly underneath the deck (2, 2'). In order to give the hull greater structural strength and make it lighter, each transverse rib (3) joined to the shell (1) is connected (103, 203) to a corresponding transverse member (4, 4') joined to the deck (2, 2') and to continuous fore and aft members (15) (girders) passing in the manner of bulkheads, so as to form a single one-piece frame with the keel member.
