I think this should be a decision made by the US F16 Class Association. It is our first "organized" class function/regatta. It is the reason the class association was formed, right? I'll ping them via email and encourage them to voice their opinions.
I agree with all of your comments and that we should be seen as an open/inviting group - but I'd rather see the Class board give an opinion.
My rules would be: 1. Same rating, class racing. 2. No whining about racing against doublehanded boats. 3. Will NOT be the F16 Midwinters "official" champ if one of them wins.
