Is it possible to resew the sail to eliminate the excess twist? I was thinking about folding certain parts
of the sail over itself and stitching it.
If it is only twist, move the leads forward. That is the primary way to control twist.
To remove fullness from a portion of the sail, generally to move the draft
forward, normally you would rip out a portion of the seam (but not the luff tape) and lap it further - folding generally does not work well.
Get a book on sail making - there are many - and you will get better advice than a forum. Many will say you can't fix an old sail, and there is some truth to that, but it is a great place to learn and the results can be pretty darn good.
