A bunch of people have also posted feedback on a sailing anarchy forum:

I generally agree with all that has been said (if you get rid of the swim rope, consider adding a couple of small marks to indicate when you are in the 'shallow' water area, kind of nice to know when to pull the boards up).

As for the Friday count/not count rule, I agree, you need to better define when to use this. I would suggest as 'there on Friday' being a boat that has either left the beach with the intent to race on Friday or checked in with RC on Friday (preferred). Don't just define it as they were here on Friday, as that leave some room for interpretation.

Simply you could require people at registration to declare if they are racing on Friday are not, no matter what they end up doing, hold them to that decision.

Offset mark, 'nough said, it needs to be there (on the spin fleet at least).

Fun event, more beer, more red cups, and more heat (less dead fish) !!!!
