Abstract
A hydrofoil system provides lift to a motor-powered displacement hull without raising the hull out of the water. The hydrofoil system includes a pair of laterally opposed forward hydrofoil wings positioned respectively on the first pontoon and second pontoon forward a center of gravity of the hull. The forward hydrofoil wings extend laterally inboard and downwards towards each other. The hydrofoil system also includes a pair of laterally opposed aft hydrofoil wings positioned near the stern of the hull on the first pontoon and second pontoon respectively. The aft hydrofoil wings extend laterally inboard towards each other and have an upper surface with convex curvature that extends from the respective first pontoon or second pontoon to an inboard terminal end thereof.
Claims22
A boat comprising:
- a motor-powered displacement hull having a deck upwardly supported by a first pontoon and a second pontoon that extend from a bow of the hull to a stern of the hull in a longitudinal direction;
- a hydrofoil system that provides lift to the hull without raising the hull out of water, the hydrofoil system comprising:
- (a) a pair of laterally opposed forward hydrofoil wings positioned respectively on the first pontoon and second pontoon forward a center of gravity of the hull, the forward hydrofoil wings extending laterally inboard and downwards towards each other;
- and
- (b) a pair of laterally opposed aft hydrofoil wings positioned near the stern of the hull on the first pontoon and second pontoon respectively, the aft hydrofoil wings (i) extending laterally inboard towards each other and (ii) having an upper surface with convex curvature extending from the respective first pontoon or second pontoon to an inboard terminal end thereof.
A boat comprising:
- a motor-powered displacement hull having a deck upwardly supported by a first pontoon and a second pontoon that extend from a bow of the hull to a stern of the hull in a longitudinal direction;
- and
- a hydrofoil system that provides lift to the hull without raising the hull out of water, the hydrofoil system comprising a pair of laterally opposed aft hydrofoil wings positioned near the stern of the hull on the first pontoon and second pontoon respectively, the aft hydrofoil wings (i) extending laterally inboard towards each other and (ii) having an upper surface with convex curvature extending from the respective first pontoon or second pontoon to an inboard terminal end thereof.
A comprising:
- a motor-powered displacement hull having a deck upwardly supported by a first pontoon and a second pontoon that extend from a bow of the hull to a stern of the hull in a longitudinal direction;
- a hydrofoil system that provides lift to the hull without raising the hull out of water, the hydrofoil system comprising:
- a first wing having a first terminal end and a second terminal end, the first terminal end of the first wing attached to the first pontoon, an attack angle of the first wing being adjustable at a point of attachment to the first pontoon;
- and
- a second wing having a first terminal end and a second terminal end, the first terminal end of the second wing attached to the second pontoon, an attack angle of the second wing being adjustable at a point of attachment to the second pontoon.
