Q. Can I have a different certificate for different sail configurations and conditions?
A. No. A boat will be allowed one configuration change only during any one season. A new CRF MkII 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).
