I'd like to know the rationale of boths parts. The idea, of course, is to please everyone here and also let the market decide what's best.

I believe you all know that the Optimist started with an extremely restricted box rule and nowadays is a strict one design with the goal to keep the price low by narrowing the limits where parents can play "who spends more on the kid's boat". I guess we can start with more freedom if convergence to the wining concept(s) is previously agreed upon.

Really guys, the design isn't the bottleneck; you all know what you are doing and all boats will be wonderful. I worry about obtaining worldwide support from multihull fleets, clubs, organizations and manufacturers, especially the last ones.
