PHRF measurements

Postby monsters inc » Wed Mar 25, 2020 4:06 am

I recently measured up my sails for the PHRF bc rating form. The mainsail is measured at 144 sq ft. (From the Sail makers info) using the formulas from sailing BC’s site my headsail (taken off a Star boat) is 60 sq.ft. My homemade spinnaker ( cut down from an old symmetrical to an asymmetric ) is 390 sq.ft.
This makes about 204 upwind and 534 downwind. Does anyone have info about their sail areas , and how this may relate to ratings? I haven’t sent in the information to the rating people yet, thinking that a smaller kite might give a better rating. Not sure how much the kite area has to do with the end result. I don’t want to end up with a rating that dumps me in with vipers or merges 24s while giving away 6 feet of waterline. Thanks all, Mike

Here is the link to my PHRF NS data sheet. The provisional rating is 150 sec/mi

My main, jib and #1 asymmetric are to the same design as the sails for the Portland OR PDX boats. The #2 asymmetric is my chicken chute. Main is 15.04M2, jib is 8.61M2 and No1 asymmetric is 39.27M2. All areas from North Sails quotation. At approx 10ft2 per M2, your white sails are slightly smaller than mine and your spinnaker about the same area.
