Performance Handicap Racing Fleet (PHRF) is a handicapping system used for yacht racing in North America. It allows dissimilar classes of sailboats to be raced against each other. The aim is to cancel out the inherent advantages and disadvantages of each class of boats, so that results reflect crew skill rather than equipment superiority.
The handicap number assigned to a class of yachts is based on the yacht's speed relative to a theoretical yacht with a rating of 0. A yacht's handicap, or rating, is the number of seconds per mile traveled that the yacht in question should be behind the theoretical yacht. Most boats have a positive PHRF rating, but some very fast boats have a negative PHRF rating. 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.
Miramar YC adheres to simple rules: submit your PHRF paper certified by North & Central Eastern United States sailing organization or have your sails and boat measured by MYC Race committee staff. Your "perf" must be submitted prior to any regattas or races captain of the boat is planning to participate in.
Boat-owner members (D-I) who just purchased new sails must inform member of MYC Race committee and submit a copy of the sales receipt for re-calculation of the PHRF.
Measuring sails for new PHRF rating calculation is a subject to a modest $15 fee, paid to MYC.
