Um, yeah, that's what Matt said...
This is a question that has been put forth at the US SAILING Spring Meeting.
Matt posted this literally while in the room in which Jim was presenting his side as to why US SAILING was pushing the Prescription.
Personally, I think we should all belong to US SAILING (for a variety of reasons, and the rule isn't one of them). For those of you who think multihulls aren't important to US SAILING, all I can say is that I heard several people, who weren't multihull sailors, pointing out to Jim that we have large numbers and need to be taken seriously (paraphrasing here).
I do think (and let Jim and the Rules Committee know) that the verbiage of the draft prescription is a disaster in terms of enforcement. Not so much for our boats, but bigger ones. Dick Rose seemed impressed with my suggestion, as it makes his life easier (I suggested they use the verbiage of the IHCA class rule regarding membership requirements).
In reponse to the questions about "paper" YCs, again, as Matt said, they are completely acceptable. The problem is, if you want a certification (RC, etc.), there is a paper form which requires a physical signature of a flag officer who recommends you. That might be tough to get from a paper club, and an officer who doesn't know you from a hole in the wall.
