OK Oz,

I've got him for awhile. Still has fight left in him. Silly Fish!

A couple of question, while I take up the slack, Jax;

If the curve of the sail has no effect, quote "None" in Newton Laws of
Motion, Then why the curve in the wing or lee side of the Sail? Why do
the Jets deploy Slots and Flaps at low speed?

Jax, That is the first of some very simple question if you know what the
hell you're talking about.

The second question; What are the tel-tales telling us on the sails?

When you, with your wisdom of ( F=ma) enlighten us on these question, we
can go into a deeper discussion;

Before I sign off, I feel an obligation to inform you adjusting the sail
curve does affect the forward motion of the boat.

Drunk or sober, there is a need to know the answer to the above
questions to take this discussion further
