I agree with your premise about one design constraints. Physics determines the optimums for any one design class... the range at the elite level will be quite small. Stay away from class politics etc etc.
Your assertion that its all about PC is just wrong.
Goal: Gender equity... Absolutely... so you must have men and women's divisions of a type of boat. Is this PC.... or Fairness.
I vote fair! (perphaps you want to debate Title IX and football scholarships in the USA)
Types of sailing. I proposed 5 basic classes.. Do you have a counter propopsal and why? (In your language which 5 turds do you want to float around in the circus) How is this choice PC?
So... The Olympic Sailing effort must afford opportunity for all of humans to SAIL... perhaps not your boat of choice... but afford the opportunity to compete in sailing. Is this goal PC... or Fair.... I vote Fair.
This means that the equipment selection must cover the range of humans when you view it as an agragate. This is not PC.... This is just a fairness issue. Notice... Basketball is not played with a team of 7 footers.
You get screwed when you stray from the core principles...
Once you stray... It will then be a matter of Political Correcness (Finn vs Laser) and just plain ol Politics... (it's hard to defend the USA when their proposal is... we only send up classes when we have a winner in that class.)
This is not PC... its just P.... and the politics is unseemly!
Remember... the Olympics are a nationalistic.. for better or worse... but that is what they are.. So... finding a cheap boat that poor countries can play with is not PC... in my opinion... it is just a matter of fairnes..
