Hydrofoil watercraft (HFWC)－particularly including extended-performance hydrofoil watercraft (E-P HFWC) characterized by a submerged demi-hull mounting hydrofoils, and also high-performance personal hydrofoil watercraft (P HFWC)－are rendered both tractable and pleasant to operate throughout broad operational ranges by the provision of selective upwards (i) flotation and (ii) planing forces from two sponsons moveable in position at the ends of hinged arms. At their maximally elevated, inboard, positions the sponsons are integrated with the contours of the...
A hydrofoil watercraft comprising: a displacement hull of a shape suitable to (i) slice through heavy seas, but ineffective to (ii) provide at a first speed of the watercraft a sufficient lifting force so as to permit the watercraft to come onto a first plane on its hull; wherein the displacement hull does not suffice to serve as a planing hull at the first speed of the hydrofoil watercraft through the water; hydrofoils, attached to the hull and extending into the water below the hull, providing at a second speed, faster than the first speed, of the wate...
