Redress may be requested by a boat or competitor that considers that the rejection or exclusion is improper or that it broke rule <%= rule_llnk('76.2') %>.

A boat shall comply with the requirements of Appendix G governing class insignia, national letters and numbers on sails. 
 

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 provides that the penalty for a breach of a class rule may be less than disqualification, the same penalty will apply to a breach of this rule.   

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 appropriate 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 appropriate committee before the start of the last day of the event, or of the first series, whichever is earlier. 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 categorization requirements, the categorization shall be carried out as described in the World Sailing Sailor Categorization Code.

When an event is rescheduled to dates different from the dates stated in the notice of race, all boats entered shall be notified. The race committee may accept new entries that meet all the entry requirements except the original deadline for entries.
