Thanks found that the other night and it seems to be very simple and fair. As well it gives some real guidelines for the measurements. Which does not seem to terribly hard to do…
It's not; you need a couple of tape measures; 2 spirit levels; some pegs to peg out the sail(s) and a little time. And ideally a helper or 2.
Huh! Talking production boats with modified sails. Between this site and Texel's site much of this is already done. The only thing we need to measure is the sails themselves and with that I may demand a certificate from the sail maker as to their square feet/meters.
Gawd...should have gone to the Harvard School of Rocket Surgery - NOT!
