In doing a recut, usually the toughest part is getting the draft
cut; where you want it, & to the best possible shape. So it pays to work with an experienced loft.
To the degree that, where once you pick out the best 3 candidates, you have the sailmaker
go for a sail with you & give them a good looking over. And then let him work his magic from there.
That, & or, set the top 3 candidates flying, both on your primary headstay, & your cutter stay, trimmed in as best you can manage (including using Barber Haulers/Twings, needs be). And then take a bunch of pictures from the angles/positions requested by the sailmaker (or a couple of good racers).
Given that, someone with a good eye for (sail) shape will be able to tell you which one(s) are viable.
Heck, if you want to post pics on here, some of us can offer up our $0.02. If so, say as much, & we can suggest what shots of the sails
to take. Though you may have to put them into an album, as we'll probably need a good half a dozen pics per sail in order to evaluate them. Along with the specs & info on each one.
Also, you do know that there are a good number of chandleries which specialize in pre-loved sails, right? The good ones even having return policies if you don't like the sail/it doesn't fit.
Plus, there are a Huge number of staysails out there with wire, or Kevlar/Spectra luffs, which are set free flying. Mostly for reaching, to off of the wind
work. But they can and do, add a lot of horsepower, when done right (SIC). And since you have free sails to work with...
And too, you could always optimize one or two of your surplus sails for reaching, when set on your staysail stay. - An extra 3/4 of a knot's good where ever you can get it
The Dashew's have some good, explanatory video footage on this. Including stuff on free flying mizzen staysails, plus mizzen spinnakers. Both of which your surplus sails could be morphed into. Only, flow in front of your main mast
, of course.
One other resource. Over the years, there have been some great articles in Seahorse,
a UK based, racing
magazine. About some of the testing done with staysails on various classes
of high end racing
yachts. Even to inclued the Volvo
boats (of some generations). And how they experimented with staysail tack positions & sail shape to optimize how much power they generated, & it was a LOT.
If you find the Dashew video footage, would you please be kind enough to let me know where you found it. As I don't think that I have their old, circa late 80's video tape anymore.
