The better the fleet, the less possibility for protests as the sailors are more knowledgeable and experienced and just avoid situations that could lead to a rules infraction.
That is true to a point. When you are racing in a really competitive fleet like at worlds etc then playing the rules becomes part of the game just as it is with any top sport.
There will always be crews who will be looking to drive you into a pinch at that level when just their plain speed is not enough. Team Booth is an example for this tactic. And honestly, while I deeply respect a more chevalrous approach to sailing, I also think that at the real top level this is inevitable. By limiting yourself to not playing this game you disadvantage yourself. That is why real top sport is not a nice occupation for alot of times.
But then again we are talking about the real top level events here.
