In the boys fleet, the next country in the line is USA as 5th ranked country at the World Championships.
In the girls fleet, the 5th ranked country at the Worlds is Germany. As Italy qualified at the World Championships, and won the Continental qualification, the place is awarded to the next ranked country from the continental qualification not yet qualified. As both Spain, France and Germany qualified directly, the next ranked country is Poland.
More changes in qualification places are still possible as some countries may decline their previously awarded places due to a competitor country quota.
Countries shall now confirm the acceptance of their qualification place to World Sailing until July 7, 2018. A registration of athletes by name must be completed by 31 August, 2018.
