Title
(EN) IMPROVED MULTI HULL WATER CRAFT
(FR) NAVIRE MULTICOQUE AMÉLIORÉ
Abstract
(EN) The present invention relates to a water craft (10) having two spaced hulls (18,20) and a tunnel (22) defined therebetween. The water craft (10) is provided with a hydrofoil section (38) extending between the hulls (18,20) and across the runnel (22). The tunnel facing side of.each hull (18,20) is provided with a recess (50) which extends from a position rearward of the bow (24) of the water craft (10) to the stern (26) of the water craft (10). Each recess (50) includes a side wall (52) which extends upwardly from the keel line of each hull (18,20) and an upper wall (56) which is inclined downwardly in the direction of the stern (26). Each recess (50) is further provided at a rearward portion thereof with a skirt (58) positioned inboard of the side wall (52) so as to define an open sided channel between the skirt (58), side wall (52) and downwardly inclined upper wall (56) of the recess (50).
(FR) La présente invention porte sur un navire (10) possédant deux coques espacées (18, 20) et un tunnel (22) défini entre celles-ci. Le navire (10) est doté d'une section hydroptère (38) qui s'étend entre les coques (18, 20) et à travers le tunnel (22). Le côté, dirigé vers le tunnel, de chaque coque (18, 20) est doté d'une cavité (50) qui s'étend d'une position arrière de la proue (24) du navire (10) à la poupe (26) du navire (10). Chaque cavité (50) comprend une paroi latérale (52) qui s'étend vers le haut à partir de la ligne de quille de chaque coque (18, 20) et une paroi supérieure (56) qui est inclinée vers le bas dans la direction de la poupe (26). Chaque cavité (50) est en outre dotée, à une partie arrière de celle-ci, d'une jupe (58) positionnée vers l'intérieur de la paroi latérale (52) de façon à définir un canal à côté ouvert entre la jupe (58), la paroi latérale (52) et la paroi supérieure inclinée vers le bas (56) de la cavité (50).
