Soon to be the subject of a Kickstarter campaign, the Subnado is manufactured by Waydoo. That Chinese company is currently best known for another type of watercraft, namely the electric foil board.
The Subnado features a 380-mm-long (14.9-in) cylindrical aluminum body that measures 60 mm wide (2.4 in) for the most part, widening to 70 mm (2.8 in) at the propeller guard. It's said to tip the scales at just 1.4 kg (3 lb).
Its 100W electric motor provides up to 6.5 kg (14 lb) of thrust, allowing a 65-kg (143-lb) user to travel at a maximum speed of 1.4 meters (4.6 ft) per second. One USB charge of its airline-approved 98-Wh lithium-ion battery should be good for up to 56 minutes of use. That battery can also be utilized to charge other devices, such as smartphones or actioncams.
