Mary,
I know the Hobie 16 does not point as well as boats with boards, so it is going to be more than a 90-degree angle when you tack to go to the mark.
OK, so, a board cat tacks for a 90-degree.
(And for a h16 i should allow for a wider angle, 95? 100?)
The question was general, i'm also interested on comments for other cats.
What about the drifting angle? asuming no currents, no waves, ..., ...
Knowing about all these things will help me to decide if I've to buy the compass, the GPS, or neither.
Thanks,
aestela.
