Title
(EN) WATERCRAFT WITH SUBMERGED PASSIVE FLOTATION DEVICES
(FR) BATEAU DOTE DE DISPOSITIFS DE FLOTTAISON PASSIFS SUBMERGES
Abstract
(EN) A watercraft has at least two narrow hulls with a shallow draft and has one or more passive flotation devices that are entirely submerged. The hulls enclose the power trains for the watercraft and are accessible from the compartments of the watercraft. The passive flotation devices do not include a power train or any other equipment requiring access from the compartments of the watercraft. The narrow, shallow draft hulls have low friction drag and produce a small bow wave. Thus, the watercraft is able to be propelled rapidly, to be propelled for a greater distance, and to be propelled efficiently by the power provided by smaller motors and lighter energy sources.
(FR) L'invention concerne un bateau comportant au moins deux coques étroites de faible tirant d'eau et un ou plusieurs dispositifs de flottaison passifs entièrement submergés. Dans les coques se trouvent les groupes motopropulseurs du bateau, les coques étant accessibles depuis les compartiments du bateau. Les dispositifs de flottaison passifs ne sont pas équipés pas de groupe motopropulseur ni d'un équipement quelconque nécessitant un accès depuis les compartiments du bateau. Les coques étroites de faible tirant d'eau ont une faible résistance de frottement et génèrent une petite vague de proue. Ainsi, le bateau est propulsé à grande vitesse, sur une longue distance et de manière efficace par la puissance développée par des moteurs de petite taille et des sources d'énergie de poids réduit.
