I'm not promoting Olympic classes at the club level - better to use non-olympic classes like the 5o5 or F18. The US adult club scene hasn't just abandoned the Olympic classes, we have largely given up on sailing anything without lead - our version of the sport has significantly reduced the level of athleticism. I believe young American athletes see this and choose to spend their time on other sports where fitness is rewarded. If we want to compete at the athletic end of the sport, then our clubs and associations need to prioritize sailing without lead.that is obviously not the direction (US) adult sailing has gone, and I'm not sure anyone should 'push' adults into equipment they don't like just because that is what the olympics picked. That is the tail wagging the dog.
A big obstacle to change here is the fact that lead-mines require much more spending on all things marine - sails, pros, boats, etc.... Better for business to define the pinnacle of our sport as the big spending - less than athletic - "owners."
