What is the purpose of a hydrofoil?
Hydrofoils are wing-like lifting surfaces that help a boat function efficiently. They’re mounted on struts below a boat’s hull or across a catamaran’s keel. Safe and efficient, hydrofoils help a boat cut through the water swiftly and smoothly. They provide a great ride with even a moderate increase in speed. 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.Foils offer a thrilling way to experience the water, combining speed, agility, and the sensation of flying above the surface. With top speeds ranging from 32-50 km/h (20-30 mph), and the ability to tailor your board’s setup to your riding style and skill level, eFoiling can be enjoyed by riders of all abilities.The hydrofoil is similar in appearance and purpose to aerofoils used by airplanes but operates in water. Unlike hydrofoil, efoil is more effort-saving. It uses power to allow people to fly on the water faster, adjust and control speed, and add technology to make it more mysterious and attractive.In addition to the environmental benefits, the electric hydrofoil has several other advantages. The batteries are relatively small, so they do not require massive charging infrastructure. They do not generate waves that erode the shoreline or wreak havoc for windsurfers and moored boats in their wake.
How fast is a hydrofoil?
Hydrofoils are the fastest water-based vehicles propelled solely by human power. They can reach speeds of up to 34 km/h (21 mph; 18 kn), easily exceeding the world records set by competitive rowing which stand at about 20 km/h (12 mph; 11 kn). Racing fastest hydrofoil boats have been known to reach speeds exceeding 60 knots (69 miles per hour or 111 kilometers per hour), while commercial hydrofoil ferries often cruise at speeds of 35 to 45 knots (40 to 52 miles per hour or 65 to 83 kilometers per hour).Hydrofoil boats are designed to decrease drag and boost efficiency by lifting the boat hull out of the water, which is especially beneficial in rough conditions. This lift allows the boat to reach higher speeds compared to slower sailing vessels and even some catamarans, as less drag means better speed and efficiency.Racing fastest hydrofoil boats have been known to reach speeds exceeding 60 knots (69 miles per hour or 111 kilometers per hour), while commercial hydrofoil ferries often cruise at speeds of 35 to 45 knots (40 to 52 miles per hour or 65 to 83 kilometers per hour).Hydrofoil boats are designed to decrease drag and boost efficiency by lifting the boat hull out of the water, which is especially beneficial in rough conditions.

Why are electric hydrofoils so expensive?
Factors Influencing the Cost: Technology and Design: eFoils incorporate advanced technology and engineering to provide a seamless and exhilarating experience. The integration of high-quality materials, sophisticated hydrofoil designs, and precision-crafted components contributes to the overall cost. Hydrofoil: The term “hydrofoil” refers to the technology of using foils on various watercraft such as sailboats, powerboats, and ferries to reduce drag and increase speed. Efoil: An “efoil” specifically refers to an electric-powered hydrofoil surfboard designed for personal recreation.Wider adoption of hydrofoils is prevented by the increased complexity of building and maintaining them.Factors Influencing the Cost: Technology and Design: eFoils incorporate advanced technology and engineering to provide a seamless and exhilarating experience. The integration of high-quality materials, sophisticated hydrofoil designs, and precision-crafted components contributes to the overall cost.The weight limit for an eFoil typically ranges from 220 to 300 pounds (100 to 135 kilograms), depending on the board size and material. Heavier riders benefit from larger boards with high-lift foil wings to improve stability, while maintaining speeds of 18-22 mph (29-35 km/h) efficiently.Factors Influencing the Cost: Technology and Design: eFoils incorporate advanced technology and engineering to provide a seamless and exhilarating experience.

What are the negatives of hydrofoils?
The hydrofoils themselves can also easily be damaged by striking debris, or they can become tangled in detritus. These designs also have much higher drag at low speeds, and can be difficult to operate in shallower areas due to the foils protruding to a greater depth beneath the surface. Hydrofoils are incredibly vulnerable to debris in the water. A big object could rip a foil off and plunge the ship downward.Operating with their foils submerged below the water’s surface, hydrofoils are prone to hitting objects floating just beneath the surface, such as logs and submerged debris. Collisions of these objects with the fully submerged foils can inflict significant damage on the boat’s structure and impair its functionality.Hydrofoiling is generally harder than surfing due to its complex balance and speed management, requiring multiple practice sessions to master.The short answer is yes, learning foil board surfing is more challenging than surfing due to the specifics of the balance involved. That’s why it helps if you have advanced surfing or kitesurfing skills before you begin your foiling journey. Even an experienced surfer needs several hours to adjust to surf foiling.
Do hydrofoils increase speed?
Hydrofoil boat hulls significantly reduce water resistance and enable higher speeds compared to traditional hull designs. Large traditional displacement boats cut through water while smaller pleasure boats utilize hull shape and engine power to partially lift themselves for reduced drag.

Efoil: An “efoil” specifically refers to an electric-powered hydrofoil surfboard designed for personal recreation.Regardless of the unfathomable terrifying above-water speeds one can achieve, the hydrofoil on the bottom of the board brings an incredible amount of lift as well. This makes it noticeably easier for the beginners to keep the balance and control compared to traditional surfing.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.Hydrofoils rise above the water’s surface thanks to their wing-like structures, which drastically cuts down on drag and boosts their speed. This is a stark contrast to traditional boats that remain immersed and are slowed by water resistance.
