Sail Numbers

Yachts racing under the Racing Rules of Sailing (ie. any boat racing under any of the rating rules we administer) must hold an approved sail number as prescribed by her national authority. This sail number shall be displayed in accordance with RRS 77, Identification on Sails.

In the UK, sail numbers are issued by the RYA or by the RORC Rating Office. Sail numbers issued by the RYA will have a L, N or X suffix (M for multihulls). Clyde Yacht Clubs’ Association numbers (C suffix) are also approved under RRS Appendix G .

RORC sail numbers issued since 1993 have an R suffix and are available in the range 1000 – 9999 (eg. GBR1234R).  The whole number including the suffix letter must be displayed on the sails in accordance with RRS 77 and declared for your IRC certificate.

You can apply for a standard 4-digit sail number through MyIRC

If you experience problems with this please contact the Rating Office.

Current RORC Members may hold a 3-figure sail number, although there are very few of these still available.  Please contact the Rating Office.
