What does a hydrofoil do for a boat?
by
Hydrofoils are the plates that bolt on your outboard cavitation plate, which increase the surface area of the plate. They work by lifting the boat out of the water as the boat gathers speed, creating less drag. This helps to increase acceleration, giving you more power and reduced strain on the engine.
“Because water is denser, a hydrofoil creates about 830 times more lift for the same area and speed compared to an airplane wing, so you can use a much smaller foil in water than air,” Raas says.
Are hydrofoil boats more efficient?
Using hydrofoils bring several advantages, and one of the big advantages is drastically lowering the impact that the FOILER has on the environment. It is not only more fuel-efficient, but it brings a whole new level of eco-consciousness.
Should I add a hydrofoil to my boat?
Installing a hydrofoil allows your boat to get up out of the hole faster and accelerate more efficiently when up on plane. Even at low speeds, you can benefit from better performance because the hydrofoil keeps you up on plane.

What is better trim tabs or hydrofoil?
Will a hydrofoil stop Porpoising?
In addition to helping your boat get up on plane faster and more efficiently, an outboard motor hydrofoil or stern drive hydrofoil from Hydro-Shield can also help solve your porpoising problem.
Do hydrofoils make a difference?
Hydrofoils work to help a boat reduce drag and increase speed. Because water provides resistance to a ship trying to move through it, the resulting pushback can make a vessel slow down, even at peak operation.
Will a hydrofoil help with cavitation?
When we talk about cavitation plates, we do not mean hydrofoils or stingray fins. These types will help with planing and bow response, but they will not do anything for cavitation.
Do Stingray hydrofoils work?
Do hydrofoils work on small outboards?
Adding a hydrofoil to an outboard does provide a performance boost much of the time. The smaller the boat the more significant the impact is, especially on boats that don’t have trim tabs.
Will hydrofoil void warranty?
Adding a hydrofoil WILL NOT VOID WARRANTY. However if it is installed improperly or breaks something it will not be warrantied.
What size hydrofoil do I need?
Wing choices
We find the optimal size wing for your average-sized hydrofoil is something between 1500-2400 cm squared, with most riders falling around that 2000 cm squared sweet spot. A lot of this is subjective to rider skill but starting a little larger will make learning easier.
What is the point of a hydrofoil?
Ships that use hydrofoils, or foils, are themselves called hydrofoils. Hydrofoils can lift a boat’s hull clear of the water as speed increases, and the resultant reduction in drag yields higher speeds without expending more horsepower. The two main foil systems now in use are the surface-piercing and submerged types.
Hydrofoils are generally prohibitively more expensive than conventional watercraft above a certain displacement, so most hydrofoil craft are relatively small, and are mainly used as high-speed passenger ferries, where the relatively high passenger fees can offset the high cost of the craft itself.
Can you sit outside on a hydrofoil?
Stay inside the broad, flat rear cabin. The outside areas of the hydrofoil are very tempting if you have a still or video camera, but once the ship hits full speed, you may be at risk if you are outside. Even when the water is relatively calm, the wind may be surprisingly strong.
How fast can a hydrofoil boat go?
In general, hydrofoils can be designed to operate at speeds of up to around 50–60 knots without incurring the significant effects of cavitation, although some will be present.
Why are hydrofoils so expensive?
In addition to the lack of production volume, foil designs change quickly, which explains its high price. Each new design needs new molds, which must be researched and developed, tested, prototyped. Supply and demand.
How much is a hydrofoil boat?
Hydrofoils are the ultimate in comfort during travel. Hydrofoils cost just $5,000 (aprox.)
