IRC Rating Rule
An IRC rating allows different designs of boats to race fairly together. Standard production boats, classics, custom designs, sportboats and high tech racing yachts are all welcome.
If you would like your boat weighed and /or measured, RORC have several measurers around the UK.
Yachts racing under the Racing Rules of Sailing must hold an approved sail number. This sail number shall be displayed in accordance with RRS 77, Identification on Sails.
