PHRF Adjustments

[T34C]

Does anyone have the list of equipment adjustments to a PHRF base score, or can you point me in the right direction to get it. I.E.... the adjustment for roller furling, smaller jib, fixed prop, etc...

Thanks.

The local web site should have some of these adjustments listed, if not, the PHRF-NW.org site does.

IIRC the adjustments are
RF +6 or 9 secs
jibs,spinnakers, main sails max 140'ish jib, ie a code 4 = +3
Code 3 = +6
No spinnaker = +18 ave, could be up to 21 depending upon code of jib
FP = +6


As examples, my base is 188, I have a code 4 jib, code 3 main and spinnaker, as such, I have a 203 rating. +6 for main and spin, +3 for jib or +15 o top of the 188. Then NFS I get an additional 21 for the NFS +3 for a code 4 jib for a total of 224.

PHRF ratings are purely local. They are handed out by a local person or commitee and the adjustments used are purely local. Find your _local_ ratings people and get the list from them. Did I mention it's a local thing?

The closest thing to a national lvl PHRF thingy:

Their directory of local authorities..:

Looks like you may be governed by either of the two fleets:

PHRF's ARE adjusted locally because some fleets are better in certain regions than others. However, I believe (not 100%) that the adjustments for things like roller furlers are more standardized. (A roller furler is the same size, speed, and windage, weight, etc... weather it is in San Diego or San Juan.)

Not to hijack, but how do I get a PHRF for a gemini?

I think you have to trade it in on one of those Macgregors you like!!!
(You may have to throw in a couple of bucks too. )

Fine, don't believe me. Read this.

http://209.85.173.104/search?q=cache...&client=safari that's Narragansett Bay's committee's credit for roller furlers, here is pnw phrf protocol change for spinnakers...http://www.phrf-nw.org/PDF.%20forms/...05-04-2007.pdf

Trust me, each local committee just makes **** up.

Chuckles,
If there is only ONE version of gemini, then using one of the links tenuki gave, to the ave, hi and lo, you are a 138 straight across the board. Seems a bit slow to me for a cat, but then again, not all of them are speed demons ether.

As far as base ratings go, they can be a crap shoot depending upon local as tenuki points out. One boat north of me, he went from a 165 to a 191, I believe is the hi number in my boats 159-191 range with an ave 172! From talking to others north of me, and a fellow on the east coast with an equal rig to mine, I do believe the credits for small sails, furling, fixed prop etc, are pretty std thru out No Am. But the base will depend a bit on local conditions etc as it should be to a degree.

The fellow north of me, per a few folks, really wined about some things. I initially was a 165 base per local club rating person, did not understand how this boat north of me could be a 191 base........found out another boat in my more local area appealed the rating to a 188. 3-6 secs I can, and do understand, but the 26 sec difference I still do not understand how it happend per say, other than my boat is about 1.5' shorter than what the manufacture listed it as along with a few other things.

The credits for small sails etc I believe are reasonably consistent. you might try to search out a fellow that IIRC name is George or may have a handle with george in it, I recall that he is an SF bay rating person, and would know better than some of us if the credits are consistent or not.

Here is the lake Michigan regulations with a 6 second credit for roller furlers without battens 3 seconds with, but it must be a production feature of the boat, and the Narragansett Bay regulations with a 3 second credit for any roller furler and any number of sails. Here's the New England PHRF committee's ideas, same as lake michigans with fewer restrictions, but boats that are production built with roller furlers _dont_ get the credit.
Northern california give +3 for any roller furler above deck with the tack attached to the top of the drum.

I believe the ratings do stick by tradition to giving things in 3 second intervals only, hence the appearance of some similitude.

There is not a 'standard deduction in north america' for anything period that I can tell, just look at the difference between every local, cushions no cushions, blah blah blah. Its some local curmudgeons making stuff up. It may not even be the _same_ local curmudgeon for your whole fleet.... (please, somebody who does phrf rating for a local organization speak up but from a national point of view it looks like a total mess!)

BTW T34C, I'm guessing the first link is the regulations document you were actually asking for, ie the regs for your area (chicago?)
