Mark,
I don't know why you associate belonging to a class with racing. There are many people who belong to class associations and do not race. They belong just because they love their boat and want to support the class association. And, because they love their boat, they want other people to be introduced to that boat and love it, too.

I don't know why it so difficult for people to understand how people can actually be in love with a particular class of boat and have no desire to keep switching to newer and younger and more beautiful designs.
