jib flapping fast

I''m sure I know why but just want more conformation.

In about 10 mph winds my working jib flaps fast at the leech. the telltales say I am trimmed right and over or under trimming does not help.

Any ideas or suggestions
thanks
James

jib flapping fast

Your leech is probably/possibly ''blown-out'' or permanently stretched.
Remedies:
1. If this is an costly sail, it can be ''rescued'' by applying a leech tape, a draw string and a cleat to fasten the draw string. -- easiest but moderate cost.
2. Alternately the leech can be resewn along by ''tightening'' the joints of the panels near the leech. --- hardest and most cost
3. Very small, short length battens can be added - ''cheap and dirty'' but small cost.

jrwright; The leach has stretched. Try tightening the leach line until the flutter stops. You should loosen the leach line again for light airs if the leach has more than an inch or two of cup in the lighter conditions. Just my opinion, George

You might also try moving the jib leads forward, so as to tighten up the leech, though this could mess up the angle of attack of the luff of the sail. It''s quicker than a trip to the sailmaker, though.

Do you have roller furling with a UV cover added along the leech?
