The Nereus - a jetski that can dive

The Nereus...at home on or under the water

YOU'RE LOOKING at the world's first prototype of an under water jetski.

Called the Nereus, the jet-ski style watercraft was designed by Mathias Koehler. The whacky-looking concept uses the wind for propulsion, which means the rider can spend as long as they like out on, or under, the water.

It makes use of foot pedals to steer and a set of pivoting fins at the base, controlled by the hand grips which are activated in the underwater dive.
