The 1900 Olympic scoring system was used. Handicaps were added to each boat's actual time to give a total adjusted time. The handicaps only had an effect in the third race.
Rozenn was penalized by the jury for touching a buoy in race 1. She was awarded a number of points equal to that he would have obtained arriving last, decreases by one point.
The races drew a considerable number of spectators and yachts to watch the races in Le Havre. The harbour was packed with different tonnage vessels. Offshore the Fleurus, Cassini, and Mangini destroyers were present. Most of the members of the international jury followed the races aboard the Almee, a yacht owned by Henri Menier.
