At QuantBoats AG, the story of a wider application of hydrofoil technology is repeated on the Lake Vierwaldstätter, this time in the form of high-speed sailing boats. On September 1, 2015, Quantboats AG of Lucerne carried out the first sailing trials with the Quant 23, a hydrofoil-equipped sailing yacht, on the Vierwaldstättersee. On its first attempt it reached a speed of more than 23 Kn (42Km/h).

The Swiss Museum of Transport has set up a number of showcases for "foil technology in the maritime sector," prominently featuring the Quant 23. The basic model was produced by Irpd AG, which prepared the 3D data and then lasered the model in PA12. In addition, the model was painted and foiled.
