I see what you mean, however, if you look where the force of the sail is
transferred to the boat, I believe that even under those circumstances, the
spinnaker would then want to turn the boat aft to lee once again. Even if
the wind was light enough not to allow that to happen, that would be what
the force would be attempting to do. Just to clarify, my argument with my
friend is, "can a spinnaker turn the boat aft to wind?". I believe the
answer is no.

I meant to practice raising your spinn.

Yes I have, but this is really a question about what the sails are
capable
of. That could occur with current with or without sails. I do not
believe
that the sails could turn the boat aft to wind while on a mooring,
spinnaker
or otherwise.

Yo Dude, did you consider a 5kt current with an opposing 1~2kt wind?

Dude, I have done my own analysis and deduction based on thought
and
logic.
