Pat makes a good point - the SI was a bad one, and far too easy to abuse from either side. It was dropped.
There are raw feelings on both sides of this issue, and a happy resolution is impossible. The RC and PC made errors - let that repeating lesson be taken to heart; If you're going to the room, be prepared for disappointment, no matter how right you are.
To stop any further rumors - there will be no appeal, but the Appeals Committee is collecting information on the ruling for "educational purposes." Maybe you'll see this case in a judges' class... it is not considered a sterling example of good judgement.
So - let it drop. Let's get back to the thread topic and not the circumstance that precipitated it:
Light air sailing is, in my opinion as a race organizer and official, an important tool to have in the box. I'm not in favor of any such limitations on how I run races. I'm definitely not convinced that "under five" is "unfair" or not a true test of skill. Separate the issues of "shifty" or "wildly shifty" from the discussion of "light." The race we're talking about was light and square - that's a fair test of skill. It's the wildly shifty races, where the 'chutes come out on the way to A-pin, that need to be abandoned.
