I assume you are talking about a mixed fleet of JAM and chute racers. We have a Wednesday night fleet and a club on our river here in St. Michaels – and have mixed fleets in each. The Wednesday folks allow a 10% PHRF adjustment for non-spinnaker. It works most of the time – in heavy air (where your and my 30-1’s would be at hull speed anyway) it is enough, in light air, not enough of an adjustment. Our courses are in pretty flat water – and end up being mostly up and down the river which is up to a half mile wide. The 10% is not enough in our rather light conditions.
After experiencing that, we made some further adjustments for the Saturday club which race down the river where there is more room. We use 15% flat adjustment for JAM and half that if you are running a cruising chute which is tacked to the bow – no sprits and no pole allowed. It seems to work better and provides a more equitable adjustment. Again, in light air, a spinnaker is a big s, but as it turns out, if you only have a small or inexperienced crew and are sailing short legs, being out there with the adjustment is better than mowing the lawn. Both of our fleets (many of us are sailing in both series) have a pretty wide range of handicaps. The fast boats are not helped very much – 10 or 15% of 100 doesn’t make much of a difference, but of 200, it does.

Frerker <rbfrer...@yahoo.com> Subject: Stus-List Handicap questions for JAM racers Greetings folks, We have a problem with how to handicap boats that race with jib and main only (JAM). The PHRF handicaps basically are for spinnaker racing. I believe that there were some clubs, a few only, that adjust numbers for JAM boats. We make adjustments to the numbers for our lake conditions and style of boat (older displacement etc.), but not sure how to fix JAM. Polars that I have seen for about 6 boats all show with chute only. Does anyone know if there are polars for downwind sailing without chutes? How can one arrive at those speeds? Could some of you whose clubs adjust numbers let me know any info you can on how that is accomplished at your club? And the rationale behind the adjustment. If it gets too specific for the whole list, we can take it offline later to keep traffic down. Thanks Ron Wild Cheri C&C 30-1 STL
