Andrew Pace
Hydrofoil boats have wing-like structures attached under their hull which lift them above the water surface as their speed increases. This reduces hydrodynamic drag, allowing the vessel to glide smoothly through the water. The hydrofoil is shaped in such a way that it generates lift as water flows over and under it. This lift counteracts the weight of the vessel, reducing the amount of hull surface area in contact with the water.

Hydrofoils are wing-like attachments that provide lift to the boat
Hydrofoils are wing-like attachments that provide lift to a boat. They are mounted to the outboard motor cavitation plate, which provides lift at the stern of the boat and prevents bow-rise. The foil is shaped in a way that generates lift as water flows over and under it. This lift counteracts the weight of the vessel, reducing the amount of hull surface area in contact with the water.
The hydrofoil's shape is designed to make use of Bernoulli's Equation, which states that the faster a fluid is moving, the lower the pressure it has. So, for a hydrofoil to move up, it must have much higher pressure on the bottom than on the top, which is achieved by moving the water on top faster than the water on the bottom.
As the hydrofoil moves through the water, it deflects water downwards, which pushes the boat up and out of the water. As forward motion increases, more water is directed downwards, lifting the boat higher off the surface. This reduces hydrodynamic drag, allowing the vessel to glide more efficiently through the water.
Hydrofoils bring the boat on plane faster, allow consistent planing at lower RPMs, and create steadier turns and higher top-end speeds. They improve boat performance and enhance stability, providing better visibility and safety.

The foil is shaped to generate lift as water flows over and under it
A hydrofoil is a wing-like attachment mounted to the outboard motor cavitation plate. The foil is shaped to generate lift as water flows over and under it. This lift counteracts the weight of the vessel, reducing the amount of hull surface area in contact with the water.
The foil is shaped to take advantage of Bernoulli's Equation, which states that the faster a fluid is moving, the lower pressure it has. Therefore, for a hydrofoil to move up, it has to have much higher pressure on the bottom than on the top, so it has to move the water on top faster than the water on the bottom. As the hydrofoil moves through the water, it deflects water downwards, which pushes the boat up out of the water (Newton's 3rd Law). As forward motion increases, more water is directed downwards and lifts the boat higher off the surface. This reduces hydrodynamic drag, allowing the vessel to glide more efficiently through the water.
Hydrofoils bring the boat on plane faster, allow consistent planing at lower RPMs, and create steadier turns and higher top-end speeds. They also improve visibility and safety by reducing bow-rise.

Hydrofoils are wing-like attachments mounted to the outboard motor cavitation plate. They are shaped in a way that generates lift as water flows over and under them. This lift counteracts the weight of the vessel, reducing the amount of hull surface area in contact with the water.
The shaping of the hydrofoils is key to their function. Bernoulli's Equation states that the faster a fluid is moving, the lower the pressure it has. Therefore, for a hydrofoil to move up, it must have a much higher pressure on the bottom than on the top. This is achieved by shaping the hydrofoils so that they move the water on top faster than the water on the bottom.
Hydrofoils also improve boat performance and enhance stability. They bring the boat on plane faster, allow consistent planing at lower RPMs, and create steadier turns and higher top-end speeds.

Hydrofoils are made of lightweight, durable materials like carbon fibre
The hydrofoils are shaped in a very specific way to make use of Bernoulli's Equation, which states that the faster a fluid is moving, the lower the pressure it has. So, for a hydrofoil to move up, it has to have much higher pressure on the bottom than on the top. This means that the hydrofoil has to move the water on top faster than the water on the bottom.
The lightweight, durable materials used in hydrofoils are essential to their function. The hydrofoils need to be strong enough to generate lift and withstand the pressure of the water, while also being light enough to allow the boat to glide smoothly through the water with minimal drag.

Frequently asked questions
A hydrofoil is a wing-like attachment mounted to the outboard motor cavitation plate.
As the hydrofoil moves through the water, it deflects water downwards which pushes the boat up out of the water. As forward motion increases, more water is directed downwards and lifts the boat higher off the surface.
Bernoulli's Equation basically says that the faster a fluid is moving, the lower pressure it has. For a hydrofoil to move up, it has to have much higher pressure on the bottom than on top, so it has to move the water on top faster than the water on the bottom.
Hydrofoils are made of lightweight, durable material like carbon fibre and are corrosion resistant.
Hydrofoils decrease hydrodynamic drag, allowing the vessel to glide more efficiently through the water. Lower bow-rise allows better visibility and safety. The hydrofoil improves boat performance and enhances stability.
