The World's First HSA Personal Watercraft

The Quadski reaches speeds of 45mph on both water and land and transitions between them in seconds. At the press of a button the Quadski's wheels deploy when approaching land and retract after entering the water.

Previously, no commercially available amphibian has been able to exceed 10 mph on water. The difference is the breakthrough GIBBS patented technology provides unique on-water performance. Unmatched freedom on water AND land, and rapid in transition - Quadski sets a new standard in flexibility, freedom and fun for personal watercraft.

High Performance BMW Engine

Quadski is powered by BMW Motorrad’s K1300 engine. On water the BMW engine is coupled with GIBBS patented water jet propulsion system. The Quadski is capable of attaining speeds of 45mph on both water and land. Excellent performance and comfortable ride are the result of a light weight composite hull, wide track and low centre of gravity, which gives Quadski robust stability on water and land.

Incorporating GIBBS HSA technology, the Quadski hull provides a stable planing surface and lateral grip for responsive handling on water. The hull is designed to be hydrodynamic in marine mode. The Quadski's hull is strong, durable, light-weight and is manufactured from a single-piece mould using current composite technology.

GIBBS jet units are lighter and more compact than traditional marine industry water jets and provide high levels of thrust and maneuverability on water. Water jet propulsion also provides responsive maneuverability at low speeds and reverse while providing power to cruise at planing speeds. GIBBS water jet technology can propel the Quadski to planing speed in seconds.

The Suspension gives superb ride and handling on land and retracts when on the water. The complete transition takes four seconds, at the push of a button.
