Notes on the significant changes and their rationale

Where no interpretation is required, but only an explanation of the effect of the class rules, it follows that it would be appropriate to deal with the original request by issuing a Q&A to be published on the IRSA website and elsewhere as appropriate.

In order to make life easier to the owners and race committees, IRSA TC decided to make a single page 10R certificate.

Scheduled activities of implementing the new single page International 10R certificate:

- Publishing date: 20 April 2019.
- Effective date: 1 October 2019.
- Existing multi page certificates remain valid and boats may continue to comply with those certificates.
- All new certificates issued after 1 October 2019 has to be made using this new Excel file.

This allows time for the authorities to view and analyse  the changes for the single page certificate and report back to the IRSA TC on any suggestions or changes.

Both the original 4 page certificate and the new single page certificate will be available on the IRSA website up until the 1^st October, 2019.
