Back:  Racing Rules

Measurement Certificates


It is a requirement, as per RRS Rule 78, that a boat’s owner and any other person in charge shall ensure that the boat is maintained to comply with the class rules, and that the measurement certificate remains valid.

International class rules require boats competing in class events to have a valid measurement certificate.  ie. a measurement certificate has been issued for the boat by the National Authority, it is registered in the name of the current owner who is a current member of the respective class association.   


Yachting Australia is the National Authority responsible for the issue and maintenance of Class Measurement Certificates and Boat/Sail numbers for some International classes (not all International classes), as per the following:































**For International classes not listed above please contact your respective class association**



New Boat Owners


Yachting Australia requires the original copy the completed Measurement Form from the builder or class measurer, and a Building Fee Receipt or the ISAF Plaque Number (you must have one or the other.)

  • Download  and complete the New Boat Registration Form.     
  • Return the completed form to Yachting Australia with the $40.00 Registration Fee along with the completed Measurement Form for the boat. 
  • Yachting Australia will update the class records on the registration database, allocate a sail number, issue the new Measurement Certificate to the owner and send a copy to the class association.

Second Hand Boat Owners

Prior to purchasing a boat for use in class racing, avoid disappointment and first check to ensure that the boat has been issued a valid class measurement certificate and the boat currently conforms to the class rules.   


Important Information 

  • Keep your certificate in a safe place, Yachting Australia may charge to issue a replacement certificate.
  • An ISAF Measurement Certificate is required to confirm that a boat conforms to the class rules and identify the current registered owner of the boat. The certificate is required to compete in regattas and class events.
  • Please note that sail numbers are NOT transferable between boats. 
  • If you purchase a brand new boat hull, or a second hand hull that has not been registered in Australia previously, you will be allocated a sail number once the relevant information has been provided to Yachting Australia. 
  • If you purchase a second hand boat that has previously been registered in Australia, you will keep the sail number the boat was originally issued with.
  • Please make sure not to leave the updating of your certificate to the last minute as processing takes some time and there are usually a few people ahead of you in the queue.
  • December/January are busy months for class events, so avoid this time of year if possible. Yachting Australia will be unable to guarantee the issue of a new certificate for regattas between Christmas and January 30th unless we have the relevant paperwork in our office no later than 5 working days prior to Christmas.
