MobyFly, a start-up based in Collonges (canton of Valais), has carried out the first sailing tests of its prototype zero-emission hydrofoil boat on Lake Geneva. This 10-meter prototype was equipped for the first time with the company’s patented retractable foil system. This was the first time that this system was used in real conditions. The results were very promising, with lower than expected energy consumption and increased autonomy.

MobyFly’s foils are streamlined rods that allow the boat to rise above the water’s surface. Thanks to this technology, the MBFY10 prototype can reach a speed of 74 km/h when the foils are lowered. When raised, it can navigate in shallow waters (from 42 centimeters) which facilitates docking and maneuvering, offering great flexibility and ease of maintenance for the operators.
