... just adapt the A-Class rules to the F12. ...
The A-class has actually one of the worst rulesets in the catamaran scene from a class stability and low-participation-cost perspective. Two pitfalls we really want to avoid in the F12 class.
It has only somewhat stabilized in the last 10 years because after 30-40 years of repeative development and significant changes to the boat the concept has found a balance that is hard to improve upon. Do we really want to see the F12 take 3 to 4 decades to find its place ?
