prohibited:
(2) repeated adjustment of the sails ...
I guess we are all disqualified all the time.
I don't know about you but on my cat I'm continiously adjusting my sails. Glenn Ashby adjusts just the downhaul about 20 times per upwind leg.
Most of the other rules are extremely hard to enforce. As such it is not fair to have these rules as the risk of getting caught is to small to be of any real concern. It will be far better to allow to these things and just call it part of sailboat racing.
