ABSTRACT:
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 select range to permit the pilot control of the attitude and roll of the craft.
