Well, at our club we decided to balance our calendar so everybody will find something:

Open racing? Fleet races(13) and Statue Race
Class racing? Hobie points and Wave event
Formula? Our Formula week end on Labor Day

Which does not prevent hobies, waves and F18/17 to race on fleet races.
Note that any outsider can participate to a fleet race. I learned recently that we are the last division 11 club running a Fleet race program (average participation is 20 boats and growing). So everybody is welcome, just show up at the skippers meeting on a race day (Calendar and club races rules at Fleet250.org).

That should work.
