The basic principle of the hydrofoil concept is simply to lift a ship's hull out of the water and support it dynamically on wing-like lifting surfaces, i.e. hydrofoils, to reduce the effect of waves on the ship and to reduce the power required to attain modestly high speeds.

DESIGN PARAMETER: Hydrofoil (It is a foil or wing under water used to lift the boat’s hull until it is totally outside the water.) What is a primary concern is the design of the foil, the struts/supports, and their positioning. All these features have to be taken in consideration. So the features are designed to...

The foils on a hydrofoil boat are much smaller than the wings (foils) on an airplane. This is because water is about 1000 times as dense as air. The higher density also means that the foils do not have to move anywhere near as fast as a plane before they generate enough lift to push the boat out of the water.

What is a hydrofoil? A hydrofoil is a watercraft that is supported on ski-like pontoons while in motion, with the bulk of the hull remaining entirely above the water (Encarta Encyclopedia 2002). The picture below shows a basic idea of how hydrofoils work as well as some different kinds If you look at his design,
