Hi

I have the opportunity to crew on a racing yacht as tactitician and
would like to learn more about racing with a GPS. Apart from the
obvious (distance and bearing to the next mark) what other uses can a
GPS be put to in yacht racing?

Speed over the ground might be an interesting statistic. It's
generally a different number than speed through the water. If there's
a current it should show up this way, and perhaps you could find a way
to either get out of it, or into it, depending on which works best for
the given situation.
