As far as befriending and crewing for monohullers. I do both on Wednesday nights.
Matt - When Art Stevens brought the Fast and Fun program through Galesville a number of years back, his one piece of advice for dealing with the clubs and other sailing groups that may not view us favorably was to "conquer from within" - join up, infiltrate, change minds, percepions and votes. Sage advice, looks like you already have that started with your Wednesday nights and other efforts. Good luck with it all!
Also, sorry for participating in the thread hijacking...
