PHRF

What is the PHRF rating for a 26S. I have raced for a couple of years in a non-spinnaker class at 222. I have done respectable. I read recently the 222 rating would be for a 26S with a spinnaker. I then found a non-spinnaker 26S rating at 242. Any thoughts on this?

222 seems to be the standard PHRF for the 26S from what I have seen, though I find no notes as to whether that is spin or non-spin. 248 seems a little high to me, even for non-spin, but if you can get that, then go for it. In my case, my sailing club assigned my boat a 228, sailing with a genoa, non-spinnaker.

I happen to be in the midst of learning about how foresail percentages affect PHRF ratings. I found an interesting calculator at https://sailingfortuitous.com/jib-calc/ that takes your foresail dimensions and distance from forestay to mast (J) and automatically determines your luff perpendicular (LP), which is then calculated as a fraction (LP/J) to give you the overlap percentage. How that plays into PHRF, I do not know.

Results are interesting...

My "stock" jib calculates to 96.21%
My genoa calculates to 141.78%
BWY's "Big Jib", which is actually 20% larger than the stock jib, actually has a lower percentage number at 94.77. Bigger sail, smaller %. Weird.

I will ask my race captain what he would rate the 26S at with a genoa and a spinnaker and see what he says.

The race captain responded as follows:

"Your friend’s boat would be a PHRF of 216 for a 150 jib and 213 for a 100 jib. That assumes a symmetrical spinnaker that isn’t oversized for the boat."

Your club's results differ.

Thank you for the info. The PHRF still seems to be a mystery. I wish I understood it. Does anyone have a source that does a good job explaining.

Wikipedia article:

Lots of information on the internet. It's complicated, but not totally inscrutable.

Can't find anything definitive. Just don't ask the folks at the Sailing Anarchy forum unless you like being ridiculed.
