Hi Carl
Perhaps you should work on the events side of the equation.
Identify 6 events that 20 foot spin boats WANT to participate in eg. Steeple Chase, C100, New England 100 Plus 3 buoy events, Tradewinds, Catfight, Something at Sandy Hook, NJ or Houston Tx. If they are three days... perhaps the remains of the Tornado fleet in the US will come out... As it is now, they have a schedule of 2 events in Miami and two events in Houston and that's it. One of the Houston events is supposed to be a gran prix type of event that the Euro guys would come over for because the season has ended in the Eu in December. What if that 3 day event included Tornado's and I20's and any other boat rated slower then the Tornado.
If you got the Builders, Harken and Several Sailmakers to pony up cash for a perpetual and cash prizes to the series winner or to the gran prix winners you might start something.
Nothing is happening now. So try two divisions.
20 feet, with a PN or Texel rating of Tornado or slower even up.
20 feet, faster then Tornado even up. Cash is apportioned according to fleet size. Consider two fees, Teams and Boats with sponsorship pay a higher fee then pure Corinthian sailors.... the extra cash goes into the prizes.
Hook up with Brian Karr and get some video of the events so that the sponsored teams have a product to show. If the pro's are coming to town... Why wouldn't the local racers come out to race. It builds interest and gives you a spectacle.
Once you get the critical mass of sailors... I suspect a consensus would emerge as to a fair set of rules moving forward.
