JMO - well done to you and your club, these boats will definitely get kids out sailing. But, I'm not sure that any beach cat classes use an air draft rule. I guess there just isn't much advantage in distorting the beams and you can fly the hull anyway via the wild thing etc. Although, most development classes now have pretty high freeboard and high beams, but mainly to avoid being knocked back by waves. Good luck - I hope you post some updates on the project.
