For Rhodysail: I cannot trust these polars. A bit too perfect values for 45, 60 and 75 degrees, if you know what I mean.

For all:
About the compass. I see very different points of view.

Asuming you're not for long distance trips, do you use a compass? Training? During the race to track windshifts?

Where I sail everybody has a compass on board. I'm now more busy trying to get speed and watching what the other boats are doing, but I guess that maybe in the future I'll have time to check the compass.
What for????

Thanks for your replies
