3 fleets, generally setup by handicapped number...
the "One Design" fleet is actually the one I'm in, and it was an attempt at getting all the ones with a similar handicap rating together... with the exception of the Hunter 25.5, it works... but the 25.5 sailor is really a pretty exceptional sailor, so they moved him into our group (he's our commodore) so that someone else could win the "racing" fleet, and he's successfully won the OD fleet a few times too, so he's certainly NOT out of place... Finally we have our "cruisers," which represent those who like to race but not enough to set a beer down, or bother with changing sails much.
Our starts are pretty nice though, cruisers first, then race fleet, then OD fleet. 10 minutes apart... so everyone (on an ideal day) finishes closer to one another. They always throw a picnic at the end of our races, people take turns doing race committee and galley duty. It's actually a pretty smart way to set things up.
Here's the breakdown of the fleets for this year. The gentleman in the "race" fleet with the O'Day 26, didn't race, because he crewed with me all season. He's a helluva sailor in his own right, and I hope he ditches that cruiser and buys to a race boat (he's a contractor by trade and his boat is like new, really an exceptional Oday 26), but then I'll lose good crew...
