The application is used to properly locate the 4 buoys that delimit a regatta course, and which is specially designed for the Seine Boat League managed by the Traditional Rowing Association, in the province of Malaga.

Through the initial establishment of two Waypoints, corresponding to the buoys of the turnaround or finish line, the application guides you so that the field has the desired length and rectangular shape.

But if when mounting the third buoy, the length of the course differs from the desired position, the application indicates the position of the fourth buoy, so that it guarantees that it is a regulatory parallelepiped.
