GYA PHRF is an outlier as far as ratings go. They have a wet vs Dry sailed criteria with a dry sailed boat being docked 3 sec vs a wet sailed boat. So while you are right the internatioal and North American organizations do not give an allowance for wet vs Dry sailed. So if you see one a t 132 it is wet sailed as opposed to 129 which is dry sailed.
And by the way while the Wed night races are not great tactical events, you can learn a lot about boat speed with this type of race. Come on out and join us.
