ABSTRACT:
Disclosed is a watercraft in which the stabilizer for the longitudinal attitude is formed of one or more hydrodynamic wings arranged by the keel, continuous or discontinuous, running from the bow to the stern, and the stabilizer of the transverse attitude is formed by one or more aerodynamic wings, the hydrodynamic and the aerodynamic wings preferably being retractable. The stabilization wings for the transverse attitude may, in the case of light hulls, be integral with the hull, which presents a biconvex outline which is asymmetrical, with the more elevated portion having a larger curvature.
