read rule in the post http://www.catsailor.com/forums/sho...ew=expanded&sb=5&o=14&fpart=

This post shows a section of the ISAF rules. Affiliation with ISAF requires you accept a pile of racing rules and equipments rules as well the rules given in the post.

In effect these rules forces you to conduct your class business a time-table set by ISAF and to ask approval in various cases. Not to mention that in several cases the ISAF may give intepretation of the class rules rather than the class organisation itself. That and the payed of 1100 Euro's affiliation fee together with 50 Euro's fee per sold class boat.
