But still the physics is the same; Thrust (sail area) plus Lift (foil surface) must overcome Weight and Drag.

So, do we need a new measurement formula that measures Thrust+Lift vs Weight+Drag?

Maybe we should look more toward how they "handicap" various aircraft against each other?

Or how do Moths compare against each other? How is that box rule set up?

My only issue with a box rule is that it may not keep boat performance close enough to challenge the sailors abilities... It could turn out like the 33rd (?) AC with the cat vs. tri blowout.. That WAS like watching paint dry. The last two iterations were much more interesting since boats were closer in performance to each other.
