The NeptunX from the company eFoilFly, is a fairly simple device following in the footsteps of other boards like the Lift & Flite eFoil’s, Made from carbon fiber, with fiberglass, EPS foam and resin sections to keep it cool enough to touch when it’s been sitting in the sun, it’s a 66-inch (1.68 m) long, 43.4-inch (1.1 m) wide board with a removable battery and a detachable, full carbon hydro foiling wing underneath measuring 31.5 inches (80 cm).
Mounted to that wing is a 48-volt electric motor rated at 3 kW nominal, 12 kW peak, and a shielded prop capable of spinning at 6,500 rpm. Stand on the board, squeeze the trigger of the gun-shaped remote, and the board will begin to accelerate, rising higher out of the water the faster you go, up to its maximum speed. It can carry passengers up to a rated 287 lb, or 130 kg.
