Compass and windex.

I really like that.

The boat I race on has these instruments. For a long time they did not
work properly, which created more confusion than results. Now they
finally work as intended, and, as the skipper says "It's almost like
cheating". The advantage is that you only have one variable to relate
to. Sounds simple but it really makes it a lot easier to get an
overview over the windpattern. Maybe a true champ would not need them
?
