hydrofoils
Wing-lifted boats
Hydrofoils are wing-like structures mounted beneath a boat's hull that lift the vessel above the water at speed, reducing drag and increasing efficiency.
The term also refers to boats equipped with these structures: The hydrofoil skimmed across the harbor.
As the craft accelerates, the foils generate lift like airplane wings, raising the hull clear of the surface.
