Hydrofoils, or foil boats, are boats that use hydrofoil technology to lift the boat's hull out of the water, decreasing drag and allowing greater speeds. They are similar in appearance and purpose to aerofoils used by aeroplanes. Hydrofoils usually consist of a wing-like structure mounted on struts below the hull, or across the keels of a catamaran. As a hydrofoil-equipped watercraft increases in speed, the hydrofoil elements below the hull develop enough lift to raise the hull out of the water, which greatly reduces hull drag.

Hydrofoils lift the boat's hull out of the water, decreasing drag and allowing greater speeds
Hydrofoils are lifting surfaces, or foils, that operate in water. They are similar in appearance and purpose to aerofoils used by aeroplanes. Boats that use hydrofoil technology are also simply termed hydrofoils.
Hydrofoils usually consist of a winglike structure mounted on struts below the hull, or across the keels of a catamaran in a variety of boats. They are like regular boats, but have wing-like structures dangling down below their bottom.

Hydrofoils are like regular boats, but with wing-like structures that lift the boat above the water when going fast
The wetted surface of a regular boat creates considerable drag when running, which in turn reduces efficiency. This drag is the main problem that foil boats can eliminate. A hydrofoil boat supports a "wing" like structure under the hull. When we look at a standard powerboat today, we see that it floats on the surface of the water. When pushed, the shape of the hull causes it to ride up and skim along on the water surface, or 'plane,' with varying degrees of efficiency.

Hydrofoils were created by Eric Walters
Hydrofoils are boats that use hydrofoil technology. They are similar in appearance and purpose to aerofoils used by aeroplanes. As a hydrofoil craft gains speed, the hydrofoils lift the boat's hull out of the water, decreasing drag and allowing greater speeds. The hydrofoil usually consists of a winglike structure mounted on struts below the hull, or across the keels of a catamaran. As a hydrofoil-equipped watercraft increases in speed, the hydrofoil elements below the hull(s) develop enough lift to raise the hull out of the water, which greatly reduces hull drag.

Hydrofoils are similar in appearance and purpose to aerofoils used by aeroplanes
Hydrofoils are designed to lift the hull of a boat out of the water as the boat increases in speed. This is achieved through a wing-like structure mounted on struts below the hull. As the boat's speed increases, the hydrofoil elements develop enough lift to raise the hull out of the water, reducing hull drag and allowing the boat to travel at greater speeds.
The concept of a foil boat is similar to that of an aeroplane using aerofoils. Both hydrofoils and aerofoils use a lifting surface to reduce drag and increase speed. In the case of hydrofoils, the lifting surface is a wing-like structure that lifts the boat above the water, while in aeroplanes, aerofoils are wings that create lift to support the aircraft in the air.

Frequently asked questions
A foil boat is also known as a hydrofoil. It is a boat that uses hydrofoil technology.
A hydrofoil has a wing-like structure mounted on struts below the hull. As the boat increases in speed, the hydrofoil elements develop enough lift to raise the hull out of the water, reducing hull drag and allowing greater speeds.
Hydrofoils are designed to reduce drag, which in turn increases efficiency.
Hydrofoils are similar in appearance to aerofoils used by aeroplanes. They have a wing-like structure dangling down below the bottom of the boat.
The hydrofoil was invented by Eric Walters. Alexander Graham Bell also worked on their development.
