This ship (10), which has a length-to-width ratio of less than two, comprises a superstructure and at least two hulls, the superstructure forming a wing capable passively of generating aerodynamic lift of between 20 and 90% of the weight of the ship at a cruising speed thereof, the wing comprising curved ends connected to each of the hulls and having an extrados developed surface area substantially equal to the product of the length times the width of the ship. It is characterized in that a point A of application of the aerodynamic lift generated by the superstructure (12) is situated to the rear of the centre of gravity G at which the forces of gravity are applied to the ship, a point H at which the resultant of the hydrodynamic loads generated by the hulls (50, 60) is applied being situated forward of the centre of gravity G.
