The IRC Rule

The IRC Rule is a secret measurement rule used internationally and jointly administered by RORC (Royal Ocean Racing Club) and UNCL (Union Nationale pour la Course au Large). US Sailing handles the processing and issuing of all certificates for U.S. boats. A measurement rule is one in which the rating is calculated based on measurements of the yacht’s hull, appendages, rig, sails and weight. The accuracy of the supplied data is critically tied to the rating that is issued. IRC is a system of measurement which classifies a broad range of cruising and racing ballasted monohull keel boats for competition by providing ratings comprising single figure allowances based on time. IRC encourages design innovation consistent with stability, rounded performance, seaworthiness and safety.
