Is my jib/genoa toast?
I have a 135 jib/genny on my P10M. No matter what I do, I can't seem to stop sail leech from luffing. I have cranked down on the leech line, moved the cars, adjusted the jib main; nothing seems to work. It luffs on all points of sail, close hauled, reach run, etc. I can get the three tell-tales all to fly straight back with proper sail trim, but the leech is still luffing.
Thanks in advance.
What's a jib main????
Is it luffing, (which I kind of doubt) or fluttering/motoring? If it is the latter and you can't seem to stop it no matter what it may be because the sail has lost its proper shape.
Sorry for the terminology. Trailing edge of the jib is fluttering/flapping, even when telltails are all straight back on the leading edge.
Jib Main = Jib Halyard. Sorry, my brain does not seem to be working.
If the tell-tales are all streaming aft pretty much equally, inside and out, top and bottom, and your leech is still fluttering, odds are the sail is a bit (?) blown. You should be able to tighten-up the leech line a bit to eliminate, or at least greatly reduce, the flutter. (Ragging on the leech line is probably counter-productive. If you close-off the leech too much, you'll reduce the performance of the sail.)
We flew our 32 year old #3 (Dacron) Sunday and what I describe above was the procedure I used. (Tho that sail has only one set of tell-tales, so I adjusted the cars by sail shape.) No flutter. And yes: That trusty old #3 is definitely a bit blown.
Btw: I suppose that by "jib main," you refer to the jib sheet(s) or jib halyard? There is no such thing as a "jib main."
My guess is that the cloth has stretched to the point you can't get a properly shaped leech... if the sail isn't that old, you could have it recut slightly to reduce the fluttering/motoring of the leech.
