Luiz,
Not sure if I understand but I see development at club level as each club will set its own rules and develop them in accordance with local requirements.

After boats come together a few times ideas will change in these groups as they swap ideas and experience learnt by the various groups as all the designs move towards converging.

Also we have to be careful to not put too much emphasis on competition. You want to hook all these kids for life. To do that they need all to feel like winners. Not one winner and a fleet of losers.
Building the community feeling will be the key to success.

Just they way I see it.

Regards,
Phill
