Hey Mark,
After thinking about this, I've changed my mind. I do believe there is a need for some sort of National Organization. However I think the scope should be expanded. I think it should be an organization not just for multihull sailors, but for sailors of all kinds. We could attempt to serve the common needs of the sailing community of the entire United States.
We can perhaps create an organization, leverage existing yacht clubs, Regional Sailing Associations, etc., to try to build a national community organization to administer the sport of sailing in the U.S..
Services we could provide to members might include:
Promote and develop racing under uniform rules
Exchange Information among sailors
Providing input to the ISAF regarding the racing rules of sailing
A certification program for judges, races officers, sailing instructors, etc.
Administration of Portsmouth, PHRF, or formula based rating/handicap systems
Providing for reduced rate Regatta and Club insurance by grouping our needs together at a National level.
Providing a forum for rules arbitration at levels higher than the local regatta (a rule/appeal system).
We could also form individual committees or groups to act as mediums of exchange of information among specific groups of sailors, like multihullers, and yet they could still be part of the larger organization promoting the like interests of all the sailors.
I suggest we all agree to meet in say... Portland Oregon, in late October, maybe the weekend of the 23rd, to discuss the idea of creating such an organization!
