We get into a P/S confrontation. I'm on stbd, you're on port. You "win" because of the SIs, but I immediately request redress because of the rule 86 violation. I win, you lose. No jury would think twice about it.
No I win because I chose the jury. If I'm going to change the rules in my hypothetical regatta I'm going to make sure the jury will go along with it. Basically this regatta would not be held under US Sailing rules. This may sound kind of crazy but it has happened. Back many years ago I sailed some races under an experimental simplified set of rules. This was long before US Sailing adopted them and that's kind of my point. If there is enough consensus and the behavior of a majority of sailors does not conform to the rules, then eventually the rules will be changed to conform to the behavior.
