A pleasure watercraft is provided which comprises a hull, sponsons, and support structures for the sponsons which have a shape of an airfoil. A cockpit for seating a pilot in the hull is located such that the distribution of mass elements in the craft positions the center of gravity of the craft within a select range along the longitudinal axis of the hull in substantially vertical alignment with seating position of the pilot, and preferably beneath the pilot. Hydrodynamic and aerodynamic forces acting on the craft as it accelerates converge within the s...


A watercraft having an aerodynamic configuration comprising: a central hull; a pair of sponsons laterally positioned one on either side of said hull; support structures mounting such sponsons to said hull, said structures having a shape of an airfoil to provide a wing section on either side of said hull between said hull and said respective sponson, a forward underside of each said structures extending substantially upwardly and outwardly from said hull to form a dihedral angle therewith; and a cockpit for seating a pilot positioned along a longitudinal ...
