In which case it is probably the luff tension; or vertical wrinkles in
which case you can try more outhaul or maybe more sheet tension.

Clew ring on the jib too big? A cruising sailor attaches the sheets to
the clew with knots :-)

As for the old sail if it was too long in the foot it is pretty easy
to cut and re sew the leech. In fact changing the curve of any of the
edges is a pretty painless job.

In the movie I can't see any luff telltails but except for the foot
looking a bit loose the sail looks good to me. But you said that you
had the outhaul slacked off.

Is that your wife? And here I thought you told me that you were some
kind of old retired guy.

By the way, if you want to learn about boating find a copy of "How to
build a Tin Canoe", by Robb White, mostly about sailing off the
Georgia, N. Florida coast but a really good read. The author is dead
now but you can get the flavor of the book by reading articles on his
web site http://www.robbwhite.com/

Aris (the fellow who owns Mariner Sails) said it was easy to change one side
or the other, but not both at the same time. So he just cut a new sail.


Thanks, Bruce. We'll keep working at it and get it figured out.

That foot looking loose has me puzzled.
Because it does. But when I tensioned it it looked worse!

We had no tension on outhaul or vang in that run.
It looks like the foot of the sail is trying to slide aft a bit.
There is no slug at the clew, and the tack fitting doesn't pull it
forward in line with the rest of the luff. It's only an inch or so.
But it might need to be retained there better. Just add a slug at
the bottom?

And I'm going to have to come up with a gate setup at the slot where
the slugs go into the mast. There is a sail stop there now, but it holds
the stack up about 5 inches. I don't know if there are more slugs on this
sail or what, but it sure stacks a lot taller when furled!

Don't add a slug at the bottom of the luff unless you know for sure that the
tack hook is in line vertically with the mast track slugs. The tack of the
mainsail may be placed so it is NOT in a vertical line with the mast slugs.
This may be due to the fact that the tack hardware sits a few inches aft on
the boom. Mine is built that way so the sail was especially cut and the tack
cringle is four inches aft of the vertical line formed by the mast slugs.

But, there SHOULD be a sliding slug at or near the clew. It should slide
easily and it should be lubed with silicone spray so it keeps sliding
easily. The outhaul should be used to keep it from sliding forward and to
flatten the sail as required. The track in the boom also needs to be kept
slippery. If you have slugs or even if you have a bolt-rope in lieu of boom
slugs. My mainsail has one sliding slug at the clew and a boltrope the from
clew to tack. This is a true shelf-foot. When the sail is bellied out all
the way the shelf assumes the perfect shape with no wrinkles. When the
outhaul is pulled tight the shelf assumes several folds that make it appear
to be no shelf at all. All told there is about six inches difference of foot
length between flat sail and full sail.

That is true in one sense. As the sail isn't flat measuring the curve
of the leech and luff is a bit iffy. Usually you stretch the side you
are changing so as to lay as flat as possible and then mark and cut
it. So I agree with the sail maker (lucky that :-). I was actually
thinking of the sewing rather then the measuring, marking and cutting.
