not sure they give a damn... Most windsurfers I know don't need or want to join the Yacht Club infrastructure that sailors with boats join and support, much less USSA. They don't seem to have much involvement with USSA and seem to to just ignore most of what USSA is doing. I am in the Farrah Hall part of the world and the stories she tells of USSA and the fiasco with the trials are awfull. So... they have such negative interaction with USSA that they would have to care before they get pissed.
