The fleet racing is run on a low points scoring system - the boat at the end of the competiton who has the least number of points wins.
All of the events finish their competition with a Medal Race, before that they are scheduled to sail 10 races, except the 49er which will sail 15 races. The boat who finishes first in a race scores one point, second place scores two points, third place scores three point and so on. Sailors are allowed to exclude their worst score in the first 10 (15) races.
After completing 10 (15) races, the top ten boats with the lowest score go on to compete in the Medal Race. The points scored in the Medal Race cannot be excluded and are worth double.
