I have not seen Dougs response. My server may not be posting
everything promptly.

It's not an easy one. This is why I made it a 15 point question.

If no one gets it by tomorrow, I'll reveal the answer and you
will all kick yourselves! Or maybe, I'll reduce the number of
points and give another hint.

Well, I had considered Doug's response, but rejected it because if the
majority
of time is spent in the steady air and a little time in puffs, it would be
more
efficient to trim for the steady air and just head up a bit in the puffs
rather
than sail with a luffing sail just to deal with an occasional puff. Plus,
if
one is motorsailing to begin with, the puffs are probably not big enough
to
cause the boat to round up or throw the boat off course close hauled in
the
first place. So, I don't know the answer.
