Abstract
A watercraft employs three or more supercavitating hydrofoils. The elements that connect the hydrofoils to the hull may flex to thus raise or lower the hydrofoils relative to the hull. The relative motion between the hydrofoils and the hull is dampened by shock absorbers or the like. A control system operated by the pilot may apply forces tending to raise or lower the hydrofoils relative to the hull. The stern hydrofoil is mounted on a support that also carries a power driven propeller and a rudder.
