Class Data for Rating System

PLEASE NOTE: for completion by class measurers.
Once the entry forms are available, and the class rating agreed, owners of one-design classes will be able to apply for their certificates through the entry process.

Where boats will sail in mixed fleets, the IRC rating system will be used to determine the results. Use this form to submit the data for those one-design classes where a standard rating may be used. Once agreed with RORC, owners may deviate from these standard measurements for their individual certificates.
