How much stretching needs to be allowed for in a new sail? I thought this was going to be easy, just measure the old sail. I have a new old-stock, full batten sail that is almost perfect in size, 28ft tall (just slightly tensioned) and unused. I need to cut it down a little at the head. It looks nice and flat exactly as new with no evidence of shrinkage. I ran it up the mast and it is maybe 4 inches too long, but it is not under tension and I don't know how much stretch to expect and allow for in a new sail. In an old sail, there can be lots of stretch. Don

That stretch makes sense. But it is because the boltrope is cut short to create an elastic edge. This is a standard sailmaking technique. It helps to control the draft position using halyard and/or Cunningham tension.
So the short answer is, how much too long is the sail when hoisted? Pull it to the top and see what is left. This would be what needs to be removed. Or better yet take a measurement with a tape measure of the max hoist. Then reduce the 27'2" length by the difference plus another 5" or so. |
