Bob - Check with your local phrf organization or sail maker. This is the formula I was given for spin sail area in sqft. See if it makes sense for you.
PHRF Rule ((SLU+SLE) x (4*SMG + SF))/12 Slu = spin luff Sle = spin leach Smg = spin mid-girth Sf = spin foot From: CnC-List [mailto:cnc-list-boun...@cnc-list.com] On Behalf Of Michael Clow via CnC-List Sent: Thursday, May 01, 2014 4:44 AM To: sam.c.sal...@gmail.com; cnc-list@cnc-list.com Subject: Re: Stus-List C$C 32 My symmetrical chute was made specifically for racing by Al Declercq in Metro Detroit so it would be the maximum legal size. My sail certificate is online below with the dimensions. Perhaps someone else knows the formula to calculate square footage? http://desiresailing.org/Misc/SailCertificateSymChute1998CnC32.pdf There is no C&C 32-II. The C&C 32 (made 1979 to 1984) is actually 31.5 LOA. The C&C99 is 32.5 feet and came out around 2000. The only similarity is that they are within .5 feet of 32 feet.
