So what world class event was this, what did all the pros attending think and why not protest since this must have been a very prestigous event where all points mattered

Having this discussion here instead of in front of a jury or better, on the beach, is a good way to not find the facts and not have the rules applied properly. Once names or places are named, discussion goes into the drain.

International problem resolution procedure:
1: Sit down together with something cool to drink and some free time. Bring many witnesses and make sure they also have something cool to drink (splitting the tab will make the lesson stick).
2: If task 1 did not solve the problem. Agree on the facts, write them down with a sketch illustrating the situation.
3: Go to the closest international jugde or similarly qualified person you trust, get his opinion.
4: Accept his opinion or go back to step 1 until solved.
5: Come back here and post the result, with pictures preferably.
6: Always remember that unless you are a pro (and a professional should know the answers so no need to ask), sailing is for fun.

Give sailors room at obstructions and dont try anything funky just before the finish line (do it well before), it will only kick back if you dont.
