Quick Summary

The International Offshore Racing Rule (IORR) is a rating rule used in yacht racing to classify sailboats of different designs. This allows yachts of varying sizes and shapes to compete on equal terms, either within specific rating classes or through a handicap system. The rules are based on formulas that measure design factors like length, beam, displacement, and sail area, all of which influence a yacht's potential speed. The IORR, introduced in 1970, combined aspects of earlier measurement rules like the Cruising Club of America (CCA) and the Royal Ocean Racing Club (RORC) rules.1
