I really do see a difference in between a foil and a wing. A foil renders the whole measurement system of a cat invalid as the submerged part of the boat is completely different.
How does it do that if the foils don't go outside the boat width? Banning foils is just plain silly. Hobby horsing is a pain as is pitching and losing the possiblity of stablising the boats with such a simple and honest device is nuts.
