Bolt ropes can shrink!
The line normally used in bolt ropes shrinks over time. This can adversely affect sail shape. If you have lots of wrinkles just behind the luff, or if your sail appears to have a hollow luff curve when spread out, the bolt rope has probably shrunk.
We sewed a new bolt rope to the bottom of the bolt rope on this sail, cut the stitches that held the bolt rope at the tack and reef, and pulled 16 inches of bolt rope into the sail. It looks a LOT better now.
