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.

You don't have a wing keel. You have a keel with end plates. In order for
it to be a wing keel the end plates must have a NACA foil section to them.
You have silly flat plates that are NOT wings.


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.

No resistance? Is that why the mainsail will stay put even if their
is only an aft force placed on the clew? If your argument was correct
the sail would also need downward force at the clew. Make no mistake,
a shelf-footed sail with a boltrope in the boom has it's shape maintained
by the foot and clew and not the clew alone as you suggest.

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.

I don't jump to wrong conclusions. It is presumptious of you to assume
you know more about my mainsail that I know about it. But, the do say
old farts get set in their ways so I forgive you your ignorance and
haughtiness.

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.

Wrong, again. The foot is supported by the bolt rope as well as by the clew.
Do you forget all about air pressure?

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

Why can't you understand you are looking it the entire picture and seeing
only a few pixels?

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.

Only when the outhaul is set such that the sail can belly out to the extent
allowed by the shelf foot. Tighten the outhaul, and the shelf foot becomes a
loose 'bag' along the boom.

If I desired to pull my outhaul all the way out so the sail is flat then
why would I bother having a shelf foot. The shape of the main is
optimal with the shelf in place.

Nice try Wally,

I would like Crappy to get the concept. Can't believe he doesn't
understand.

a free footed sail an awful lot of strain is put on the Boom slut.

Now, English isn't my first (or second) language....but somehow I've a

Neal,

That freedom of the Hong Kong people granted by the Chinese Communist
Gov is the reason for the Cargo Containers Loaded with the refugees from
Hong Kong trying to get into our West Coast and Canada, I guess they
just can't stand that much Freedom. I can't seem to remember people
fleeing like that under the British Rule, mostly because it wasn't
happening.

Neal.

Thanks for speaking up for the Old Man but you're just talking back to
'Net Static with distorted repeats of sent post. Simply tune it out.

You can't use logic with STATIC. Tune it out!
