This month, the Arizona-based startup announced that another e-vehicle will be joining its lineup – the WAV personal watercraft.

Its name an acronym for Water Adventure Vehicle, the WAV is reportedly slated for a 2020 launch. Although little has been released in the way of specs, they may end up being similar to those of the Gratis X1 – it's an electric stand-up personal watercraft designed by Free Form Factory, which was recently acquired by Nikola.

What we do know about the WAV is that it features a "wakeboard architecture" that results in sport bike-style ergonomics. Its electric motor produces instant torque, and all of the electronics are protected by an IP68-rated waterproofing system – that means they can withstand being submerged to a depth of 1.5 meters (4.9 ft) for half an hour.
