A lot of areas use +12 for no spin. Some use +12 for no spin on fractional rigs and +18 on masthead. Some even go as far as +18 on all. Pick a number and go with it. If it is a light wind day likely the spin boats will win. If it is windier than maybe the non spin Have a fun race. A lot of people like the Pursuit format since you see more boats on the course throughout the day Mike

I can't envision a way that this would turn out well. Seems like you need two fleets or a course that has little or no downwind legs. You could also just say no handicap for non-spin or just not allow any spinnakers. I'm thinking very few, short, downwind legs is the best answer if a mixed fleet is the only option.

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.
