this would work almost..
Grandfathered boats need conform to the "grandfathered class rules".. The question would then be .. Can a Tiapan 4.9 (with wings) sail in a official T 4.9 regatta as a T4.9? If not then the boat is not grandfathered and must conform to all F16 rules... Quite simple really..
True, but i could make a Viper narrower, put wings on and still meet the F16 class rules, have greater leverage and have the wings extended out the back of the boat to help "launch it" downwind.
