Yes, as long as you have to use MC as a crutch to set speed so that
you get max glide, the above is absolutely correct. Downwind you
should set MC negative (if you can )


I believe the program in the SN-10 doesn't take into account the drift
correction angle which was considerable with the 25 knot cross-wind I
had on my final leg home. I was holding a good 10 degrees heading up-
wind as the ship tracked Parowan. This gave me much more of a head-
wind component and I believe the comuuter didn't compute on the 'real'
heading that would be required to track the destination into a stiff
cross-wind.
What do you thing?

I do not know what SN-10 does, but yes, cross wind component is very
important if you worry about wind.
