Abstract

L'invention a trait à un navire multicoque, comprenant une pluralité de coques supérieures (1) ayant des entretoises de coque et pouvant se déplacer vers le haut et vers le bas, une pluralité de coques inférieures (3) ayant des entretoises de coque, une pluralité de coques intermédiaires (2) ayant des entretoises de coque ou partageant des entretoises de coque avec les coques inférieures (3), et un cadre fort (5) reliant lesdites coques. Lorsqu'il est nécessaire de réduire l'influence des ondes sur un navire multicoque, le navire multicoque peut être transformé en un navire multicoque de petite surface de plan d'eau, et le navire multicoque est bien adapté à la tenue de mer.
