The Quadrofoil is a revolutionary Slovenian-made vessel, a new type which, according to the idea leader Simon Pivac, is to nautical what the arrival of the Jet Ski was to the jet ski. It glides on the surface of the water similar to a hydrofoil, i.e. it lifts its hull out of the water, and navigation is ensured by underwater wings with the bionic shape of whale fins. It is an electric, economical and environmentally friendly vehicle with operating costs of less than one euro per hour of driving.
