ORC International and ORC Club certificates may be issued by any ORC rating office in the form of an ORC One Design certificate. In these certificates all data affecting a boat's rating are standardized based on the set of measurements for classes having One Design class rules or having all the measurements in close tolerances. For these certificates no measurements are needed provided that there is proof supplied to the rating office that the boat is complying with its One Design Class measurements.

Any change of the boat or its rig, sails or crew from One Design Class measurements shall render invalid the boat's ORC One Design certificate and a new standard ORC International or ORC Club certificate must be issued.

Please note that One Design measurement data may be changed from time to time due to changes in the Class Rules, the IMS Rule or the ORC Rating system rules. Currently available ORC One Design certificates are listed below together with an ORC Club One Design certificate sample.

If your boat complies with One Design Class rules in one of these classes, you can get an ORC One Design certificate with no additional measurement required. Simply fill-out this on-line form , and the request will be sent to the relevant ORC rating office who will then contact you if they have any questions about your application before issuing you your certificate.

Fees for ORC One Design certificates will vary by rating office, contact them for any questions - a list of ORC rating offices can be found here . If there is no ORC Rating office in your country the certificate will be made by the ORC staff in the Central Rating Office who will contact you by e-mail.
