Just a few observations so far.
Forget windsurfing, they have their own set of rules which allows air rowing and touching the mark so no comparison with dinghies. etc.
However, Rule 42 does indeed have an effect on fair racing if you know how to do it correctly which might include not being within the rules. People are generally frightened of protesting and certainly loud observations about someone else can work just as well. It is possible to police and certainly from a jury boat it is much more clear, especially if you are a dinghy sailor. You would be surprised how clear it can be when watched from a few hundred yards away.
Generally if it is being effective then the probability is that the sailor knows what he is doing even if he denies it. Some classes do indeed turn the rule on and off and just because it says you can does not mean you should. Watching another day at the Contender Worlds it was noticeable that many boats were pumping like mad because the flag was up and going slower because of it, where as the skilled guy with one pump (or at the most 2) at the right point of the wave left the others standing.
The ISAF rules can and do work and David is right when he refers to the skills of people like Larry Marks. Like so many of the rules, they do not appear to work because no one makes them work by protesting etc. Sailors always have excuses why it wasn't them!

Pat is right with her RRS 3 and it is a shame that more people don't read it, equally right is the reference to Fair Sailing which is RRS2. Gentlemanly conduct is called sportsmanship and is part of the RRS 69 which is where you life starts to get very complicated if you have failed to act in the correct way.
However, I was referring to the term "Rules" in the definitions sense which covers a lot of things including the RRS, ISAF regulations, Class Rules, Notice of Race, Sailing Instructions, National Authority Prescriptions etc. So I still wonder it there is a particular rule or set or rules which start the very concept of fair competition. No one has mentioned it yet.
