Please read the letter again. The question is not how do we fly a spinnaker
while moored, but rather is it at all possible for a bow-moored boat to be
be turned around by a spinnaker, or any other combination of sails for that
matter, so that the aft end travels upwind?

I am of the opinion that this is physically impossible and that under no
combination of sail at a mooring could the boat turn around so that the
aft
was upwind. I am of the opinion that you could get the boat to swing to
one
side or the other a bit by backing the jib, but you could still never
turn
the boat around.

I would gratefully accept as many informed opinions as possible on this
from
a sailing or physics point of view.

We are disagreeing about fundamental behaviour characteristics of sailboats.
It has extended beyond our discussion of how to deal with a spinnaker into a
situation where we disagree on what is within and without the realm of
possibility. So, as competitive men are wont to do, we are trying to settle
it. So, do you have an opinion, or you going to Zen master me into a
frenzy?

Think of a boat sailing on her mooring. Does not the aft end follow the
bow? As she sails across the wind -tied to the mooring -does she not
advance a little way up wind before stalling and tacking off again?

Does that help you think more clearly grasshopper?

Excuse me, but O find your whole question totally illogical. Why even
suppose that it could? There is no advantage to or purpose in doing what
you ask. And it oddly sounds like a Bobsprit question.

That's so dumb it begs a kick in the rear....it is not difficult to catch a
mooring ball from the bow or from amidhips....if you got some crew that knew
what they were doing you wouldn't have these problems....

My deck is too high for anyone to grab a mooring ball. You can grab
it with a dock pole, but you can't reach down far enough to tie a line
onto it.

And what then?
Drag it up to the bow?
How do you manage to hold the boat against a decent breeze, especially
when it turns beam on to the breeze?

You're not very bright, are you? You tie a line to your bow cleat,
and bring the other end back to the swim platform. The preson on the
swim platform ties that end onto the mooring ball. Then he goes up to
the bow and pulls the boat in.
