I don't think they got it from US Sailing. I can't even get them to reply to any emails after they gave me a mandated number to use for the Nacra 20 Carbon a few days before last years Florida 300. They still have not posted the provisional rating yet.
You still haven't answered my question:
I was not there either so forgive the NOOB info request. I did homework and only have hearsay. Was the Nacra Foiler able to foil at all or was it foiling and lost a lot of time due to having to stop and reverse to clear seaweed?
I was told that they were not foiling until the way back. I am going to pass on the info to US Sailing for all the good that will do. I am about done with them and thinking of using another rating system for next year.
