There could always be subdivisions within the US Sailing boundries. That way people don't feel forced into driving 3 days away to compete, but they can still be competitive on a local level. IIRC, thats kind of how the Collegiate sailing structure.

I know where were in North Point->SAISA then the broader nationwide collegiate sailing organization. To qualify for "regionals" you had to place in the top 4 in North Points, of which consist 3 regattas.
