For years. at least on Lake Ontario, the normal size of a symmetrical spinnaker was 183%. PHRF-LO at the time allowed up to a 183% before a rating adjustment.
You may have 183% spinnakers. I have rarely measured old spinnakers and managed to get the original dimensions within 1%. Michael Brown Windburn C&C 30-1 I should have mentioned, my spinnakers' max widths are both "only" 184% of J. Randy ----- Original Message ----- When I bought C&C 30-1 HIN 3007972 it came with two spinnakers of different material weights. They were handed down with the boat when the PO moved it to Colorado from Traverse City Michigan (where it spent the first 40 years of its life). The lighter one was made by Babel & Buchbinder, an obscure loft in Traverse City that now appears to be a Doyle loft (http://www.doylesails.com/lofts/traversecity/). I can't find a sailmaker's label on the heavier one. Both have "ChuteSCOOP" dousing sleeves on them (http://www.chutescoop.com). That's all I know about them. I measured their max width how my RSA's PHRF chairman told me to, by folding each sail in half vertically and measuring from the trailing edges to the center fold, both at the foot and about a third of the way up. Then I doubled the measurement and calculated what % of J it represented. If that's not the right way to measure SMW maybe I can get 6 seconds back in my PHRF rating :) Cheers, Randy
