International Rating Certificate (IRC) is a system of handicapping sailboats and yachts for the purpose of racing. It is managed by the Royal Ocean Racing Club (RORC) in the United Kingdom through their dedicated Rating Office, [ 1 ] and the Union Nationale pour la Course au Large (UNCL) in France.
If Boat A has a PHRF rating of 15 and Boat B has a rating of 30 and they compete on a 1-mile course, Boat A should finish approximately 15 seconds in front of Boat B. Results are adjusted for handicap by the race committee after all competitors have finished. Each region has its own variation on PHRF rules and ratings, based on local conditions.

Each boat's time is adjusted with the formula, and then the adjusted scores are compared to determine the outcome of the race. For example, a PD Racer (a semi-open homebuilt class, and the slowest listed boat in the USA scheme) has a D-PN of 140, and an A-Scow (the fastest listed centreboard boat) has a D-PN of 61.3. If an A Scow takes 1 hour ...
