Steve Corona has written an excellent background article on the origins of PHRF-LO.  Called Handicap Analysis

This well describes how the organization came into being, how the early determinations of handicaps were made, and how increasing sophistication of the review of assigned handicaps and assigning of handicaps has developed.  The vital question is - where do we go from here?  This is a matter that has consumed considerable time for your executive in the recent past and has two parts that have developed from Steve's article namely, assigning new handicaps and reviewing existing handicaps.

What is the "Traditional PHRF Racer/Cruiser?

Performance Handicap Racing has its origins in the late 1970s and has been designed around fleets of traditional racer/cruisers and cruiser/racers. These yachts have relatively similar performance characteristics on the various points of sail (beat, reach and run) and in varying sailing conditions (wind strength and sea condition).

PHRF handicaps are BOAT PERFORMANCE HANDICAPS. They are based upon the SPEED POTENTIAL of CLASSES of yachts. They are supposed to be determined from the actual observed performance of yachts on the racecourse.

PHRF handicaps are not intended to be a Skipper or Crew handicapping system or to compensate for poors ailing ability or inadequate equipment. (as in golf handicaps)

Every PHRF-LO class that races over the past 5 years.
For "grouped" classes by design over the past 5 years.
For "Interclub events only" over the past 5 years.


In all cases, a significant amount of time and effort is put into the decision process. Many resources are used including:
