Off topic, but I just learned this recently after getting into a discussion with a college racing team person. The person that was ooching was not cheating by college rules, and most probably aren't informed that they have their own set of rules so they don't know any better.
You are correct. College racing class rules modify RRS 42 (Propulsion). You are also correct that college sailors trained to employ kinetics don't always know that those actions are not allowed under normal racing rules. I once saw a senior judge pull a competitor aside and read him the riot act about his kinetics infractions on the water. He was a very good college sailor (and later became a professional sailor) but did not realize that the very actions he was coached to perform were prohibited by the RRS.
Another senior judge once told me that the ISAF Rules Committee were so unhappy with the college sailing rules, that they considered adding rule 42 to the list of rules that cannot be changed.
For what it's worth (probably nothing), in the anecdote I related, the boat was sailing on a beat to windward in little to no wind (certainly not planing or surfing conditions), so even under college sailing rules, ooching was prohibited.
But, even that wasn't my point. I was trying to express that as competitors, we are self-policing. When referees and umpires are not present to enforce the rules, we must accept a higher standard of behavior and follow the rules without external compulsion.
If you want a role-model for sportsmanship, look at ultimate frisbee. The competitors pride themselves that they are entirely self-policed - even at the olympic level.
