you dont have to buy the $2000(not installed) boards!

The A Cat is a developement boat, rigid sails, curved boards, carbon everything, but....they drew the line with foiling. Why? Im sure cost is a factor, but bringing the A Cat to a true foiler would really make alot of boats obsolete. A big percentage of A Catters are sailing on older platforms, probably enough to sway the vote to keep it a more "traditional developement class".
Comparing it to the Moth's probably not fair, at least in the US the Moth is not a very widely raced boat, so therefore stepping it up a notch probably didnt limit alot of boats(at least here in the US)
