Where a Rule Authority exists in the country in which you are racing (see list on page 64) all IRC applications and correspondence must be directed through that Authority – they effectively act as our local agent. Your country may not have a Rule Authority yet, in which case please contact the RORC Rating Office for advice.


See www.ircrating.org for international information, including the Rule, measurement (including simplified measurement guides), committees and race management guidelines.


For application methods, forms and fees please check with your Rule Authority as they may have specific application methods or requirements.


Application process


1. Contact your Rule Authority, or look on its website for IRC application information.


2. Submit your application.


3. Payment is made direct to the Rule Authority. There is an extra fee if the certificate is needed within five working days.


4. The Rule Authority checks the application and forwards it to the Rating Authority (RORC or UNCL).


5. The Rating Authority processes the application and returns the rating certificate to the Rule Authority.


6. The Rule Authority forwards the certificate to the boat’s owner or representative.


7. Check your certificate and report any possible errors to your Rule Authority. Remember that standard hull data may have been applied.


The TCC (rating) IRC is a simple Time on Time system, and the TCC is a multiplier applied to the actual time taken to complete the race. Elapsed Time x TCC = Corrected Time; the shortest corrected time wins.


The higher the TCC, the faster the boat is. To work out how much time boats give each other, see the Real Time Calculator link on www.ircrating.org.


Sail measurement for Endorsed certificate For sails built since January 2011, for boats requiring an Endorsed certificate in GBR and some other countries, sail measurement data is only accepted from an approved sail measurer or a sail loft approved for ISAF IHC (In-House Certification).


For more information on IHC, and to find out which sail lofts have already met the standards, see www.sailing.org/ihc/index.php or contact your Rule Authority to check whether your measurer is approved for measurement.
