I help out with a local charity regatta called Pirates on the Pungo. http://www.piratesonpungo.org We are planning to do a couple of special trophies this year, one of which will go to the C&C sailboat that finishes first in the long pursuit race on the first day of sailing. While we plan to have both spin and non-spin classes for the PHRF boats in the regatta (with sub classes to keep the competition fair for all size boats), we want the special awards to span both spin and non-spin.
NCPHRF, unlike some other regional PHRF groups, does not grant different spin and non-spin ratings. And the PHRF base ratings that we use for a lot of the casual sailors presume a spinnaker. So we're thinking about creating an adjusted "NON-SPIN" rating for the boats in the special trophy groups that will let them compete relatively fairly with the spin boats in the same special group. I've been told that one of the clubs in Oriental, NC adds an arbitrary 11 seconds to the NCPHRF spin rating to get a "non-spin" rating - regardless of the size or type of boat. That doesn't sound like it would be fair to the smaller boats like the 24, 25, or 27, and it might be generous for the larger boats like my own 38 or Charlie Nelson's 36XL. During the past couple of weeks there was some discussion of how various clubs and local groups calculate a "non-spin" rating that lets all boats race in one class. I seem to recall one message that indicated 10% or 15% of the normal rating was added for a boat racing non-spin. But I think there were other methods, too. So the question for the wisdom of the list is this: What is a fair way to adjust the normal PHRF rating (which presumes a spinnaker) for a boat that is racing non-spin? Thanks for your input.
