Re: Stus-List PHRF Reviews and Adjustments

[Donald Kern via CnC-List]

Being on the Narragansett Bay PHRF Rating Committee I can state that we do review boat performance regularly (monthly meetings).I did not realize how difficult it is to rate boats ranging from the latest high-performance racers to 1919 Herreshoff S class boats.The committee consist of sailing professionals, sail makers, boat builders, engineer, statistician, and a 'good old boat' owner (me).

The committee, in an effort to keep the Narra. Bay PHRF rating rules relevant, compatible with other rule systems _and_ making PHRF more attractive to boats outfitted with cruising sails is modifying our rules for 2020. The most significant rules change is that ratings will be adjusted for all sails based on their actual sail area. This will account square-top and large roach mainsails, cruising spinnakers / undersized spinnakers and owners purchasing secondhand sails.Genoa adjustments were already based on area and the range of adjustment has been modified to better account for observed performance. I have attached extract from Narragansett Bay PHRF documentation on how the committee functions and its guidelines.
