On that page you can also find hints on which sails should be used in which wind. Regarding the wind angles that should be sailed, keep the arrow indicating the wind direction green. All courses, upwind and downwind, are sailed with the same sails. The only thing that may make a sail change necessary is the wind strength.
Sail 1 is used when the wind force is above 20 knots and sail 2 is used when the wind force is below 20 knots. The boat is fast, and you need to react quickly. It is a good idea to zoom out on the radar to see the boats on the radar earlier.
Please keep enough distance and avoid contact with other boats. During buoy roundings the foils may touch the buoys without a penalty being given.
