I'd be interested. I think there is real difference in how 'active management' might work.... are you managing real boat ratings, or handicapping skipper/crew. I guess a fleet has to agree on what the 'right thing' is. ;^) Our spin fleet would have a problem with the latter, but our non-spin fleet might be OK with that.
I am managing boat ratings.
We have a spinnaker fleet that consists mostly of J-boats. They use their one-design rating. I'm not touching that.
The cruising fleet is mostly JAM and maybe a spinnaker or two. It is the cruising JAM fleet that I am adjusting.
Here are the changes I made:
1. Adjusted Base PHRF rating +6, based on what is typically published by US Sailing and most other PHRF sites
2. Increased Inboard Propeller credit from 3 to 6 seconds
3. Maintain the 12 second credit for non-spinnaker
4. Maintain a 3 second credit for roller furler
5. Added a 6 second credit for using all Dacron cruising sails (JAM)
6. Allow 3 second credit if foresail is 130% to 145%
7. Allow 6 second credit if foresail is less than 130%.
A sample of the adjusted PHRF ratings are:
Catalina 22 Sport = 264 decreased from 270 ODR
Catalina 22 = 282
Catalina 25 = 261
Hunter 216 = 240
S2 7.3 = 261
S2 6.9 = 231
Precision 23 = 267
Seaward 26 = 264
Ranger 22 = 237
MacGregor 26 = 267
O'Day 23 = 276
Long story, but the C22 Sport and the Seaward 26 are my "scratch boats" for the JAM fleet. These two boats have been the top performers, and have also competed very effectively against the J-boat fleet when all boats shared same start. Can't really equalize the JAM and spinnaker fleets...but I can at least bring a little more balance over a period of many, many races.
