Coordinating a season's sailing schedule is always tough ....
Here in the "mid-atlantic" area Hobie Div11 and CRAC have been working for years to try and produce a yearly schedule that works for everyone. Add to that the CBYRA's "Big Boat" series, Annual YC's One-Design Regattas, and Junior's racing schedule and it gets complex. How it is accomplished here is that Hobie Div11 scheduling meeting is attended by Open Class representatives (Mark Schieder) and we all work together to try and organize the schedule ... note that some years we are more successful then others ... but it takes alot of work and communication ... starting in September/October of the preceeding year.
