Abstract

A lifting device ( 10 ) for watercrafts of the fully planing or semiplaning type provides at least a transversal element ( 15 ) constrained to the bottom ( 25 ) by means of supports orthogonal to the waterline (8) and suitable to increase the hydrodynamic lift acting on the bottom ( 25 ). The position of the device ( 10 ) may be under the barycentre ( 5 ) or slightly shifted from it, and generates, when in navigation at a sufficient speed ( 4 ), an additional hydrodynamic lift (6), which adds to the hydrodynamic lift ( 3 ) on the bottom and to the hydrostatic lift ( 2 ) for balancing the weight of the watercraft. The transversal element ( 15 ) is arranged substantially parallel to the watercraft bottom ( 25 ), so that in fully planing or semi-planing conditions it is inclined with respect to the speed ( 4 ) of the watercraft. This way it is possible to reduce the amount of water displaced during navigation and to supply a steady hydrodynamic lift.
