Just to be clear--It's just a white line that ripped out of the seam in the jib
leech--probably about 1/4" thick nylon rope
. It looks like its purpose was to keep the leech in the right shape (not luff as I said earlier). The rest of the leech seems fine. That's not fatal, is it? The sail is probably as old as the boat--20 years but was never used very much. How much does a jib that fits into a roller fuller cost for a 38 foot boat?
