I have to agree with Bob.

At the many, many Hobie NAs, Alter Cup events, etc. that I've raced and officiated, the one common thing that I take home is that there's very little screaming, people do circles (or sail well enough to avoid the issue), and generally are nice to one another on the water. Yes, I've seen exceptions (that were taken care of in the room); but overall, sailors at this level are not intentionally cheating.

At the Olympic event that I worked last week, I saw plenty of examples of great sailors sailing well, doing turns as needed, etc. There were a number of protests, but that's why they bring in the big guns to run the jury.
