Hey there,
Sorry for the late reply, I have not had access to my computer for the past week, and have had a brief chance to log on. Sailing races will be sorted by fleet class, and national teams are allowed to register up to three boats, with the condition that they must be of different classes. There will be a Star Class race, a 470 Class race, and a 49er Class race. All classes use two person crews, and may be unisex if so desired (not mandatory; there will be no sex segregation in the racing component). Once again, a nation may field one boat in each race with crews of two people.
