I'd also recommend going to the Hobie Class Association website and looking into holding a GEP seminar in your area. Here's the link:

It's basically a one day seminar (Friday) before a big event in your area where you will most likely have the greatest # of sailors attending. It starts with a talk in the morning and drills in the afternoon. The guest is usually a top ranked sailor such as the Alter brothers, Wally Myers, Kirk Newkirk, the Korz's, etc. Well worth it for your fleet/division to consider.
