Abstract[English]
Embodiments of the invention provide a displacement hull watercraft that has at least two pontoons, or two pontoon sections in the case of a unitary hull watercraft. The watercraft can recover energy from displaced water to aid in forward motion of the vessel. Advantages are reduced drag through pressure recovery owing to the long, slender stern of the pontoons or pontoon sections. Drag is further reduced at speeds below the hull speed through the close spacing of the pontoons from each other with respect to the pontoon width.[French]
Des modes de réalisation de la présente invention concernent une embarcation à coque déplaçable qui a au moins deux pontons, ou deux sections de ponton dans le cas d'une embarcation à coque unitaire. L'embarcation peut récupérer de l'énergie à partir de l'eau déplacée pour aider au mouvement vers l'avant du navire. Les avantages sont une traînée réduite par récupération de pression en raison de la longue poupe élancée des pontons ou des sections de ponton. La traînée est en outre réduite à des vitesses inférieures à la vitesse de la coque grâce à l'espacement réduit entre les pontons par rapport à leur largeur.
