Yes you can. But, I think they can cause problems on light weight boats that responsed quickly to wind
speed changes. As the boat
speed changes quickly the apparrent wind
direction changes causing the wind vane
to respond. This can cause the boat
shift around alot and go into irons or other issues. This is also supposed to be a problem on performance monohulls.
I am sure someone else has a better understanding and could explain it better.
