A hydrofoil is a lifting surface, or foil, that operates in water. They are similar in appearance and purpose to aerofoils used by aeroplanes. Boats that use hydrofoil technology are also simply termed hydrofoils. As a hydrofoil craft gains speed, the hydrofoils lift the boat's hull out of the water, decreasing drag and allowing greater speeds.

Jan 6, 2020 · Wikipedia describes it as a “lifting surface, or foil, that works in water.” Basically, it’s a wing-shaped underwater fin that lifts whatever craft it’s on out of the water when it reaches a minimum speed. This significantly reduces drag which in turn increases speed. A Brief History of Foil Surfing.
Aug 31, 2000 · Seakeeping. Some of the principle advantages of hydrofoil ships, over all other monohull or alternative ship types are: (1) the ability of a ship, which is small by conventional ship standards, to operate effectively in nearly all sea environments, and (2) an improved ratio of power to displacement in the 30 to 50 knot speed range permitting ...
