Already have the rules in place to limit the effects of hydrofoils. Not the best of rules, but extremely discouraging if you want to go down that path.

In regard to the wing. The C-Class cats have 2 on board and the crew is fairly busy tuning the wing. Different dynamics in that you control twist and yaw. Doing that on a 1-man boat whilst steering and holding the main is going to be the biggest factor for Ben Hall to overcounter. In straight line he may be the quickest when he gets it going, but changing gears and getting round the course going to be another matter and will take a bit of training. Only 6 weeks really to go now. I think this will be his biggest challenge to get over, not some overzealous bunch changing the rules.
