Electric hydrofoils, commonly referred to as eFoils, are electrically powered watercraft designed to lift above the water's surface using a hydrofoil system. They typically consist of a buoyant board, an electric motor, a submerged propeller, and a hydrofoil assembly mounted beneath the board. As the rider gains speed, the hydrofoil generates lift, raising the board above the water and reducing drag. Most models are controlled using a wireless handheld remote, which allows riders to regulate acceleration and speed. Different designs vary in board dimensions, battery capacity, motor output, and foil configuration to accommodate different experience levels and riding conditions.
eFoils are primarily used for recreational water sports, offering an alternative to traditional surfing, paddleboarding, and other board based activities. Because they rely on electric propulsion rather than wind or waves, they can operate on lakes, rivers, and coastal waters under suitable conditions. Their ability to travel across relatively calm water makes them accessible in locations where conventional wave dependent board sports may be impractical. However, performance and usability depend on factors such as battery runtime, rider weight, water conditions, and equipment configuration. As a specialized category of personal watercraft, eFoils combine elements of electric mobility, hydrofoil engineering, and board sports.
Waydoo’s Flyer EVO Pro Plus uses a unique Smart Flight Assistance System that holds the board at a set height and manages motor power. Andrew tested whether it teaches riders to fly or just does the work for them by bringing Zac Darnell to the lake, an expert electric unicycle rider that had never been on an eFoil prior to this experience. With assistance on, Zac stood up in three minutes and held a ten second flight at the ten minute mark. Once Andrew switched it off, Zac flew on his first try with zero crashes, after only about 40 minutes on the water in total. Some throttle flutter in turns, a two bolt mast mount and no included board bags or prop cone hold it back slightly, but at $6,500, it's a well-rounded board that beginners will appreciate and more seasoned riders will also love.
