German Slider

The maritime solution

The german slider is a new type of ground effect vehicle based on Jörg's principle, which combines state-of-the-art technology, ecology, economy, and design in its forward-looking conception, as well as continuously developing these components scientifically and sustainably. At present, this is the most effective maritime vehicle, not only in terms of its speed capabilities, which can reach up to 7 times the speed of a conventional watercraft.

The german slider travels at three different speed levels: Displacement, Glide and Float or Flair. Until flair mode is reached, it drives like a conventional motorboat, then makes the best possible use of the ground effect and moves along hovering just above the water surface.

Interieur Study


The Wing-In-Ground-Effect (WIG), is a physical phenomenon discovered by U.S. Air Force pilots during World War II and used by some bird species for thousands of years. The ground effect refers to the lift created by the dynamic pressure between the surface of the water and the wings, which allows the bird to rise into the air and glide close above the surface of the water with little energy expenditure.

In the history of the development of ground effect vehicles, the German researcher and engineer Günther W. Jörg has a special position. Jörg, who had already played a major role in the development of the vertical takeoff, has set completely new standards in the field of ground effect vehicles with the invention of the Tandem Airfoil Flairboat (TAF). Its special design results in a self-stabilizing effect.

The German Slider has been successfully developed over 20 years and is the first vehicle of its kind as well as the only self-stabilising WIG-Effect vehicle in the world.

Ecological benefits

The german slider uses a new type of technology that has significant ecological and economic advantages. Since the vehicle moves above the water, no marine life or plants are affected.

Furthermore, its soundless movement protects noise-sensitive marine in-habitants. Its non-existent draught prevents injuries to animals such as whales and dolphins, which frequent occurrences with other types of marine vessels. Moreover, the german slider produces no wave impact, thus protecting animals’ breeding grounds on river banks.

The german slider not only saves 80-90% of the fuel, but also achieves up to 7 times the speed compared to conventional maritime vehicles. The speed that can be achieved depends on the size of the vehicle: starting at 140 km/h for our 14 meter model and rising up to 500 km/h for our large vehicles.

The vehicles will also be available with an electric drive and a hydrogen engine for the first time, making the german slider even more economically efficient and completely emission-free.
