Q. Can I have more than one CRF certificate with different data declarations (e.g. different sail configurations) that are valid for racing at the same time?
A. No. A boat can have just one valid certificate and one pair of spinnaker/no spinnaker ratings at any one time. A boat will be allowed one configuration change (e.g from a big genoa to a small jib) during any one racing season. A new CRF certificate reflecting that one change must be issued at least 10 days before the next race in which the boat competes, and the boat may not revert back to her original configuration later in the same season. This ‘one change’ limitation does not preclude correcting errors or making minor updates to declarations, which may be accepted and a new certificate issued, at the discretion of CRF administration.
