Owners of boats based in Great Britain (including the Channel Islands) can now apply for their RORC sail number through our MyIRC online system, where you will be able to choose your sail number from a list of those still available.    

RORC issued sail numbers are identified by an 'R' suffix.  Standard numbers are 4 figures but RORC members are entitled to a 3 figure number; to see more details about this and compliance with the Racing Rules of Sailing, please click here.     

Please note that we cannot issue GBR sail numbers to boats based overseas, even if British registered; overseas boats should contact their local Member National Authority to obtain an appropriate sail number.
