such a club or organization, or
a member of an ISAF member national authority.
Competitors shall comply with World Sailing Regulation 19, Eligibility Code.
76. EXCLUSION OF BOATS OR COMPETITORS
The organizing authority or the race committee may reject or cancel the entry of a boat or exclude a competitor, subject to rule 76.3, provided it does so before the start of the first race and states the reason for doing so. On request the boat shall promptly be given the reason in writing. The boat may request redress if she considers that the rejection or exclusion is improper.
The organizing authority or the race committee shall not reject or cancel the entry of a boat or exclude a competitor because of advertising, provided the boat or competitor complies with ISAF Regulation 20, Advertising Code.
At world and continental championships no entry within stated quotas shall be rejected or cancelled without first obtaining the approval of the relevant ISAF Class Association (or the Offshore Racing Council) or the ISAF.

A boat shall comply with the requirements of Appendix G governing class insignia, national letters and numbers on sails.
78. COMPLIANCE WITH CLASS RULES ; CERTIFICATES
While a boat is racing, her owner and any other person in charge shall ensure that the boat is maintained to comply with her class rules and that her measurement or rating certificate, if any, remains valid. In addition, the boat shall also comply at other times specified in the class rules, the notice of race or the sailing instructions.
When a rule requires a valid certificate to be produced or its existence verified before a boat races, and this cannot be done, the boat may race provided that the race committee receives a statement signed by the person in charge that a valid certificate exists. The boat shall produce the certificate or arrange for its existence to be verified by the race committee. The penalty for breaking this rule is disqualification without a hearing from all races of the event.
If the notice of race or class rules state that some or all competitors must satisfy classification requirements, the classification shall be carried out as described in ISAF Regulation 22, Sailor Classification Code.
A boat and her crew shall comply with ISAF Regulation 20, Advertising Code.
