recutting my blown out main
Jeez, Jeff. You are a brave man; especially if you can''t afford to replace the sail if you screw up. First of all, the maximum draft should be quite far forward. Normally as a sail ages, it is the leech that stretches and as it does the point of max camber migrates aft. Recuts rarely take anything out of the luff. They are normally broad seamed cuts (curving on one panel and not the other) that occur at several panel seams and extend from the leech of the sail going forward of the center of the sail. Doing a good recut takes quite a bit of skill and judgement to do well and avoid ending up with ''Frankensail''. A well executed recut is actually harder to figure out what to do than to design a whole new sail which in a good loft is done on a computer. My best suggestion is to befriend someone who works for a sailmaker and pick their brain.
