Abstract

Hull with variable geometry for a vessel (11), comprising a completely immersed part (12), configured to provide part of the buoyancy thrust and integral with an emerged part (13) of the hull by means of one or more uprights (14), and one or more immersed wing surfaces (15) which, in a situation in which the vessel travels at a sufficiently high speed, are configured to provide the remaining part of the vertical thrust required to keep the vessel (11) above the surface of the water at a predetermined height; the hull comprises one or more supports (16a, 16b, 16c) connected to the wing surfaces (15) and associated with floating elements (17a, 17b, 17c) which are mobile with respect to the completely immersed part (12); the floating elements (17a, 17b, 17c) are fixed to the supports (16a, 16b, 16c) or mobile with respect to the supports (16a, 16b, 16c), therefore the floating elements (17a, 17b, 17c) are substantially cooperating with the completely immersed part (12) and with the wing surfaces (15); the wing surfaces (15) are configured to move with respect to the completely immersed part (12) or to remain fixed with respect thereto and the floating elements (17a, 17b, 17c) are configured to increase their immersion as the speed of the vessel decreases, and therefore provide the vertical thrust to maintain or adjust the distance of the vessel from the water in a manner that is optimal and functional for the use of the vessel, even at reduced speeds or when the vessel is stationary.
