Buoy Zone is designed to help sailing clubs, Race Offices and support vessels, lay yacht racing courses. The Race Officer sets a course from the start boat and shares this course with their support boats and other participants. The participants can see the course on a map, get course updates in real-time and all support boats can also been seen on the map. Any boats laying marks can zoom in on the map and see exactly where to lay their marks, or tap on a mark for real-time compass direction, bearing and distance. Take the time and pain out of setting an accurate course, and get on with the awesome racing.
