Buoy Zone is designed to help set and lay offical yacht racing courses. The race officer sets a course from the start boat and shares this with the support boats. The support boats can "Join the course" view the course on a map and clearly see where to lay their marks.

Any boats laying marks can zoom in on the map and see exactly where to lay their marks or tap on a mark for a compass direction and distance, making accurate mark laying simple and quick.

The race officer can update the course and any point and all support boats will get course updates, in realtime.
