Will be very interesting to hear from someone who actually used the Chopper!
I have 3 Naish boxers. Two from 2007 4.4m and 5.0m; both rig on 370 and 6.2m from 2010, rigs on 430. I really like them. 6.2m has amazing wind range. I jump straight to 5.0 when the wind picks up.
2007 Boxers were more compact than latter models. If I had 5.4m boxer from 2007, I could rig it on 370 mast.
Kauli became numero uno with one
Would also be nice if someone who has the Chopper could measure the actual sail area using some simple technique similar to measuring fin area.
