So we need to schedule a North American Championship prior to Worlds so that all the international sailors can get themselves sorted out? I'm laughing, actually, out loud.

Honestly, I'm sure it will be up for a class vote, and then submitted to the host club if necessary. There is already a warm-up event scheduled - Labor Day regatta. My suspicion (based on history) is that there will only be a few teams that can afford to take the time to do both. Stacking on another event? *shrugs*
