A hull structure of nonmetallic material, in particular of a reinforced plastics material, for boats, ships, minesweepers and the like, comprises a preferably one-piece shell (1) and at least one deck (2, 2') and has a plurality of ribs (3) which are distributed along the length of the hull and extend across the corresponding transverse section of said shell (1) and a plurality of transverse members (4, 4') (known as beams) which extend directly underneath the deck (2, 2'). In order to give the hull greater structural strength and make it lighter, the invention provides that 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. The invention achieves the aforesaid object to a still greater degree by means of additional improvements. <IMAGE> |
