According to Mike's post the RC announced at the competitors meeting that a DSQ would be awarded for violators. So if it was said it needs to be enforced or anything said at the competitors meeting can be simply disregarded. There is something to be said for "Mean what you say and say what you mean!"

Now if they were all in the exclusion zone then yes all penalties need to be enforced. It's easy to present missing a mark it's somewhat harder to show that someone was on the wrong side of an imaginary line, not all boats have trackers.

This whole idea of assessing penalties on the fly after the fact is bullsh!t anyway, it never works out and things like these are VERY easy to make black and white.
