Abstract: A ship having a length to width ratio smaller than two and including a superstructure and at least two hulls, the superstructure forming a wing able to generate an aerodynamic lift comprised between 20 and 90% of the weight of the ship at a cruising speed thereof, the wing including curved ends connected to each of the hulls and having a developed surface of an extrados of the wing substantially equal to the product of the length by the width of the ship, wherein a point for application of the aerodynamic lift generated by the superstructure is situated behind the center of gravity for application of the gravitational forces on the ship, and a point for application of the resultant of the hydrodynamic forces generated by the hulls is situated in front of the center of gravity.
