The only sensor needed to determine the tacking angle is a compass. Even our newbie
poster understands that - its baffling that Neal does not. I suspect he has never tried
to go upwind.

Aboard, one must always tack through the apparent wind. This
this is because while aboard nothing else exists for the observer
until the yacth comes to a complete halt. Then and only then can
the observer aboard the vessel know both the true wind speed and
direction.

Bull****. Any reasonably competent set of sensors can do this easily,
on a continually updated basis. We display both apparent and true wind
speed/direction all the time.

Of course, we actually know how to program computers to integrate data
from multiple devices, not just wander off to the West catalog with
credit card in hand and buy something that doesn't do what you want.
