The 2019 World Championships is the most important regatta for sailors outside of the Olympic Games.
For the worlds best it is the best measuring stick for how they stack up as a fleet. Teams doing well will be the ones to beat in Tokyo, and their countries will deliver the resources needed to take aim at Tokyo for those who they think can win a medal. A bit farther down in the fleet, there are also at least 15 Olympic qualifying berths on offer from the three fleets. Only 20 teams per fleet make it to the Olympics, and many top sailing teams are still not qualified for Tokyo. Qualifying is a 3 stage process, where the first berths were awarded last year at the 2018 World Championship in Aarhus, and the 2019 Worlds is the second stage. The final stage is called continental qualifying, and it will occur in the spring of 2020 on each continent.
