What's the reason for the black line on the jib?

It's like training wheels for idiots that can't understand how to read a
sail.... great idea for someone sailing with a "Chinese junk"....

Gives some indication of sail shape? Seems redundant if
that's what it's for.

Its so you can see the chord shape of the sail... Try slacking or tensioning
the haliyard and observe the way the curve of that line
changes...
Moving the sheet lead will change the twist and set of the sail
and try to lose the slight hook in the leech.....its not good......slack
the leech line off some . .
If you would only stop waffling on about how great you are and take a little
time to learn..you might get the best from your new sails

.. they look like they COULD be a surprisingly good cut... (for the price)...
cartainly adequate...

Enjoy!

You may need to pay attention to forestay tension because the draft is
way back for an unstretched new sail. Either that or it's cut badly..

There's no need. he's not racing and would prefer not to have to keep
adjusting it as the wind picks up.

Neal,

James has given you a damn good appeasel and where you are out of
adjustment

Lets you and I talk a little about sail trim,
head sail trim.
That line is to let you see the curve of your sail, parallel to the
deck. It shoes your trim. Most salts use the seams on a cross cut but
the line is better

Adjustments on the head

Sag------Is the amount of slack in your forestay. controlled by back
stay tension

Twist------ The amount of fall off of the sail as you lok aloft

Shape (Chord)-----Controlled by Sheet car position, Sheet
tension,Halyard tension and leech (roach) length

If you look at your "Line" you will see a definite hook leading into the
leech. It is a indication of to tight of a leech. Someone mentioned
Leech string tension, Ease off on it until you get a flutter in the
roach and then draw up on it just enough to stop the flutter. The hook
should disappear Check the back end of your line

Strange that only you and me spotted that eh?

Cheers MC

It's so you can easily see sail shape, particularly at night.
You can see from that pic that the draft is waaay to far back.
Either that or you got a spinnaker cut headsail.


Oz1...of the 3 twins.
I welcome you to crackerbox palace,We've been expecting you.

Sorry Neal, hit the wrong button

Anyway
Part tow;

Sag Starting position; there should be about three inches sag when you
look up the forestay with the sail on ( this is kind of a seat of the
pants setting) It is to create a bend in the sail. Light air--more bend;
Hvy air -- less bend. Up wind no bend. This is a back stay adjustment

Sheet position; The sheet car, to start, should have the sheet
bisecting the angle of the tack corner equally. This will let you
control the twist and shape of the sail.
Light air more car forward to get a baggy sail; move it back to get a
flatter sail for hvy air and ease sheet tension to get more twist ( to
relieve pressure aloft)
This may have been the the only adjustment you had correct. he top
windward tell tail should just be dancing

Halyard Tension should be used to shape sail, especially the upper half
and position the depth location of the Chord

That is enough said. Now the sling and arrows of the racing group can
let fly.
It takes and old man with little sense to even try to sell sail trim to
anyone, let alone a group

Looking at the main sail, I have to agree with Nutsy, you do need help
and it has damn little to do with boom bend, You need to get that Lump
out of the Tack area. Get more tension on your outhaul for sure. Get a
picture of the whole sail from your dingy and then we'll see what we can
do.

Forestay is very tight. I did not uphaul the sail very much because the
wind was so light that a slack luff was necessary. I tried uphauling it
more on a reach but the luff got sort of a kink in it instead of a nice
smooth curve. When I slacked off on the halyard tension the sail
shape smoothed out.

S.Simon - knows how to shape the sails on his own boat better
than some wannabe looking at pictures.
