Re: Sizes of genoas
I just looked at the West Florida phrf Rules, and APPENDIX C addresses Adjustments To Ratings. Paragraph 1.0 says a sail measuring more than 155% and up to and including 165% has a -3 adjustment. If those are the rules under which you are racing, your sail should be ok, as being within those parameters.
Nevertheless, as you can see, measurements should be very carefully made, because any inaccuracy can, at the least, be embarrassing, and at the worst, it can be embarrassing AND cost you a victory.
