Important notes
• In Switzerland a driver’s licence is required to use boats with more than 6 kW of power or with more than 15 m2 of sail area.
• A theory and a practical exam are required. The theory exams are the same for both powerboats and sailing boats and the test questions are the same all over Switzerland.
• The official offices conduct theory exams.
• The way questions are put on App is very close to the way they are at the official exam.
