Wow, is this confusing! Clearly, most PHRF districts have different interpretations of the ramifications of sail size, pole size, and sail material on rating. A few quick questions:

1. What is the rating for a one design equipped boat in the Chesapeake Bay (ditto other regions)?

2. What is the base PHRF rating for the same boat (i.e. 155, J length pole etc.)?

3. What is the rating for an unrestricted S-2 9.1 (to my mind, the closest performing PHRF boat raced in many regions)?

4. How about the J-29 Masthead Outboard rating?

5. Same questions for any other rating territories?

6. Does anybody adhere to (or try to adhere to) the YRALIS 1260 pound weight limit? I have trouble imagining a J-30 in 20 knots of wind racing with that weight.

7. Do all boats racing with a ODR setup strictly adhere to all OD rules (i.e. anchor, stove, cushions, bin covers, headstay length, sail purchse limitations, sail weights...). OK, no one will honestly respond to this one I think!

And to follow up on my own thoughts...

Why would anybody in YRALIS opt for a ODR number? Seth and Joe have opened my eyes (and restricted my inventory as a result) to the concept of a slight advantage in rating by adherng to class limitations.

Seems that a changing (and regionally different) PHRF rule will simultaneously force me to cede ground to my PHRF competitors and toss a very good sail in the garbage. Anyone want a lightly used 1/2 oz. chute?

The Chesapeake Bay had a nine second PHRF-base/ODR difference 18 years ago (3 sec 163% genoa, 3 sec oversized pole, and 3 sec larger spinnaker). I based my sail purchase on that difference in 1986 because there were few J/30s racing in Hampton, VA. I was on the PHRF handicappers board ~1989-1992. The total difference dropped to six seconds. Three J/30s were actively racing PHRF-base at that time. In 1998 I returned from three years in Charleston to find that the PHRF-base/ODR difference was zero! Throughout this time period J/30 Class rules have been relaxed, allowing higher tech sails (note feedback poll on the J/30 web site). Something is amiss in the Chesapeake Bay. Several ODR boats have entered the Hampton arena. On the water experience shows that a nine second difference is about right.

Sounds like PHRF-MA is unique in allowing +3 benefit for a ODR, i.e., 138, versus the more common 141-3-3 ala carte PHRF rating. I don't know what inspired the ODR versus standard rating, but it creates the technicality that any non-OD change, even if not normally a penalized change (like sail material, chute weight), prohibitss the boat from carrying the ODR - instant cut to 135. The loophole at the margin is what the class defines as OD, not what PHRF penalizes. I would sail 135 with non OD sails, except I can't afford the double inventory and would like to sail a few OD events per year. Would also like to know along with Steve the rating of S2-9.1s in other districts.

Yes, always in intersting question... J30 v S29.1

Lake Mich J/30 OD = 138, 9.1=132

The Chicago fleet I race in has it's own PHRF ratings

MORF J/30 OD = 135, 9.1=132

These are for the standard rig 9.1, not the shorter masts, which are 135.

For what it's worth, I am buying new sails for the J/30 I bought last August. Exchanged emails with PHRF NE Measurer. I am going with 163% overlap and J measurement pole. Rating is supposed to be 138 in that config. ie; 144 base less 6 for 163% overlap. In ODR config it would be 135. 144 less 6 for overlap and less 3 for pole penalty.
