So.... in answer to what does US sailing do for its members... not its customers..
Besides the things that Multihull sailors take for granted or dismiss... like Race Management training, and the Multihull Championship Committee, or the Olympic committee.
there is also a One Design organization.... who are doing this....
US Sailing's 2013 One-Design Symposium: A Learning Experience US Sailing's 2013 One-Design Symposium, presented by Gowrie Group, is coming to the Cleveland Yachting Club in Rocky River, Ohio on January 11-13. Enjoy more than 20 workshops and general sessions at this premier event for one-design class racing.
Workshop and presentation topics include:
Racing Rules and their tactical uses Growing your class and staying strong Go Fast Tips from experts Best resources for your class, club or fleet Attracting young adults Regatta overview Class Communications Sponsorship, Digital Marketing, Brand Management Successful Fleet Checklist
I will say it again.... it's a club... If you value one of the things the club is about..... you should support the Volunteers.
I would bet that your local club or YRA just can't pull together this kind of program...
I attended the Annapolis OD symposium and though it was spectacular... I even wrote up lots of notes and put them on cat sailor...
