Wouter, getting the ratios right is the challenge for the designer. As I see it, the formula just defines a box to work within.
If the goal of this class is to provide an opportunity for some experimentation and development, the parameters of the envelope need to be large enough. Hence, I dont see a reason to limit mast height. Yes, let the uni-rigs play as well, then we will know if they really are the best on distance racing as well. Personally, I think a jib is a very good thing to have on a boat for distance racing.


As for minimum weight, I have sent some messages to some knowledgeable persons (both designers and builders) to ask what they think a sensible minimum weight should be. Hopefully they have the time to answer.
