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?

I've raced dinghies and cruised yachts so I'm familiar with general
tactics and how to use GPS, but I need to put the two together.

Thanks for any help.

A.
