If the Fee to race is raised to provide the prize then you will not have new racers in the events. I would try it a few times but there is usually someone that wins all the time and a few that win if that person does not show up Prize racing is for the elite sailor that believes he/she will recover the entry fee enough times to at least break even. I do not like snobs or generally unfriendly people and would stay away from prize races if I found them there. It is also possible that prize racing and media coverage would attract new people into racing that would not have previously thought about it. I would think this is a distant possibility given the years of practice that it would take to get competitive. (Sailing is not like stock car racing). My opinion is knock yourself out and see how it works.
