How do wing surfboards work

Fliteboard: Cool surfboard with an electric drive

Is that cool or not? An electric surfboard! The fliteboard from the Australian manufacturer of the same name works like an electrically powered hydrofoil. We introduce you to the unusual eFoil concept.

More electric mobility on a small scale:

The fliteboard consists of the surfboard and an electric motor with a propeller on a kind of keel that plunges into the water. The storage lithium-ion battery (the so-called flite cell) allows surfing adventures of up to one and a half hours (for a water sports enthusiast weighing 80 kilos) and speeds of up to 45 km / h.

In contrast to other eFoil surfboards, the electric motor on the Fliteboard is not located in the surfboard, but in a torpedo-shaped element at the lower end of the keel. So it is cooled by the water. Another advantage: If the motor is defective, you don't have to send in the surfboard, only the lower element.

The board is controlled via a waterproof remote control. This Flite Controller, is held in the hand while surfing. The device also shows GPS data, speed and charge status on its LCD display.

The engine output is regulated with the index finger via a kind of trigger. Alternatively, there are 20 power levels that can be activated using a plus and a minus button. The driver does not have to cramp his index finger to keep the pace.

If the angle of the board is abnormal (for example, in an accident), the motor will stop immediately. For safety reasons, the motor does not work outside the water either.

The fliteboard logs and saves about 30 pieces of data, five times per second. These can be used to diagnose problems if there are problems. The planned Flite app for your own mobile phone should also enable the user to view the driving data and share it with friends on social networks. Software updates for the Fliteboard will then also be distributed via the cellular connection - Tesla also offers such over-the-air updates for its cars.

Three different versions are offered: Fliteboard, Fliteboard Pro and Fliteboard Air. The Fliteboard is the entry-level model; it measures 1.73 meters by 71 centimeters. The 1.52 meter by 62 centimeter large Fliteboard Pro is the board for advanced users. The Fliteboard Air is inflatable and therefore particularly portable. It measures 1.98 meters by 76 centimeters.

With the non-inflatable boards you can also choose between three colors (light gray, black and wood look) and between short and long keel (60 or 75 centimeters).

In addition, you can choose the type of stabilization through different wings (at the front end of the underwater element): TheCruiser wingensures buoyancy even at low speeds and stable surfing even at low speeds. TheFlyer Wing increases stability at medium and high speeds.

Two battery sizes are offered: Sport (1.65 kWh) and Explore (2.10 kWh). Two chargers can be ordered. It charges the battery either with 20 amps in about three hours or with 25 amps in two hours. The prices for the fliteboard start at 13,420 euros (including delivery).
