Two examples that will illustrate the issue. TBCS ran their hangover regatta Jan 1/ 05 . 26 or so boats. 10 boats with Spins in the same start and run the same course. They score 2 fleets of 5 spin boats??? They do not calculate overall 1 through 10 on handicap.
This weekend at the Upcoming Tradewinds regatta. Rick White announced he will have 6 starts for 50 boats??? Probably: two for the spin boats. With 10 F18's and 10 20's and the one F16 will be tossed in with the a different fleet.
To me this is one start and race called the spin class scored on handicap and two one design divisions(F18's and I20's). A 21 boat race seems a lot more interesting to me then a 10 boat one design start.... One result is certainly that the F16 doesn't have much incentive to travel any great distance to race the other non spin boats.
