Now, it looks certain we'll see a commercial electric-powered hydrofoil surfboard on the market in the form of Lift Foils' new eFoil.
The power of the eFoil electric hydrofoil surfboard is controlled by a wireless hand controller and the rider's "body English," with the waterproof controller using Bluetooth connectivity and designed so that it floats if it should be dislodged from the rider's hands.
The eFoil has a top speed of 22 knots (25 mph), and deliveries will begin in September of this year for US$12,000.
The eFoil board will initially be available in two sizes: 168 cm x 71 cm (5 ft 6 in by 28 in) for the standard E1 eFoil, and 152.5 cm x 63.5 cm (5 ft 6 in by 25 in) for the E1 Sport model. "The standard eFoil is more stable with the bigger deck, while the smaller board is more nimble and turns quicker," according to Lift Foils founder Nick Leason.
