Nice pics but I don't see much of anything but shoddy workmanship on the clew
of your mainsail. Sure there is some webbing sloppily sewn to the somewhat
weak and puny clew patch but that means little or nothing.

http://captneal.homestead.com/newsails.html

Please note how the clew of my mainsail works as a system. The bolt rope
has plenty of holding power which spreads the load while the sliding slug
is attached firmly with webbing. There are eight (count 'em, eight) layers
of 6.9 oz American made Dacron reinforcing the clew and the clew cringle
is machine pressed through all eight layers. The layers get progressively
larger so that the largest patch is a full three feet from the clew itself.

The sail will tear in half at it's mid point long before this sturdy clew
is even stretched significantly.

That's what you get for being cheap.

Good American sailcloth lovingly sewn in Hong Kong using a combination of
machine and hand-stitching from dedicated Chinese factory workers produces
a product superior to the North Sail, for example, that is farmed out to Mexican
and commie Korean workers who have never even seen a sail boat.

Are you saying that the Chinese aren't commies?

Last time I looked, Hong Kong was a free, capitalist society
with no commies in charge of anything. Hong Kong used to
be a British Colony. Good Grief!

Neal,

I'm not sure you truly understand your main sail. That bolt rope on the
foot of a shelved main give NO SUPPORT! A shelved main is a free footed
main and anchored only at the TACK and the CLEW. That shelve is an
elastic material which is designed to let the full airflow shape of the
sail continue to the bottom of the sail. It is the assure that the air
doesn't form a vortex at the Boom. The material is meant to be loose
enough to let sail shape carry to the foot of the sail.

All those layers of of cloth mean didderly without the stitching to
prevent the shearing action that take place at the Clew corner. The slug
is a nice feature but a Clew Strap is something you should install. With
a free footed sail an awful lot of strain is put on the Boom slut.

Neal, my friend, you have a weak Clew on that sail.

Ole Thom
P/S Neal, stop kidding yourself that the shelve is working as a system
for STRENGTH. It isn't!!

Thom,

I'm not sure you understand MY shelf-footed main. It has no elastic material
comprising the shelf. It has the same 6.9oz Dacron as the rest of the sail. It
is the shape of the panel that constitutes the shelf foot that gives it it's shape.

The bolt rope definitely gives the foot of the sail support as it slides into the
internal track in the boom. Note in the photo how the sliding slug and the bolt
rope line up. Both keep the foot onto the boom and have the added virtue of
spreading out the forces over a greater area than with a clew only like your
set-up.

My friend you have a weak understanding of my clew and sails in
general. Anybody who can even abide a roll-up headsail proves he
has low standards and is willing to compromise performance for
convenience, which convenience leads to all sorts of additional
problems usually at the very worst times.

And, of course, all those layers at the clew patch are sewn together.
Done properly, which they are, those webbing straps are as unnecessary
as tits on a boar hog.

Well Neal,

You're proven you inability to accept the truth about the action of a
"Wing Keel", the fact of a low profile PH, the advantage of a furler on
a cruising boat, and now the actual operation of your own Main Sail. The
scope of your known ignorance continues to grow. Explanation seems
hopeless.

I will try, once again, to enlighten you. Your SHELVE, it has excess
material so that as the foot of the sail forms its curve there is no
resistance applied by the shelve. As you flatten your sail, the shelve
folds on itself. This is what I refereed to as an elastic action. If you
knew what the hell the shelve is doing you wouldn't be jumping to WRONG
conclusions.

Your sail's foot is only supported at the TACK and CLEW. You have the
same support as you would have if the sail was REEFED. There would be no
support from the Folded Part of the sail. That is the best example I can
think of right now.

Neal, your new main IS A FREE FOOTED sail/ with a shelve. Why can't you
understand that a shelve give no more support to the foot of the sail
than the reefed section of the sail
