Jerry,
Thanks for the link. This is a definite improvement over the
previous generation Omer wing sail, particularly since it's one sail
instead of three panels. Very nice demos of the sailing and
raising/lowering/reefing.
However, I can't find any information on it. I'm particularly
interested in how the camber is controlled. The camber on the old
Omer sail had to be set manually every time the sails angle of
attack changed, which was one of the things that eliminated it from
my consideration. The video makes the camber appear to be either
automatic or largely automatic, but it's tough to tell with that
brief animation in the middle.
What inspires me most is seeing the sail work. I'm still a fan of
the swingwing junk rig, and since I was pondering flexible rear
sections and a rotating boom (I know I'm not the only one), it's
great to see a version of this in action.
Looking forward to more information when Onesails posts it.

Rob,
I think you have seen this already:

My question is would the round section mast be easier/cheaper to build than the normal D section like you have been doing? Notice the diameter is the same all the way up, could you make this by going over a pvc pipe mandrel or such? I think it would be hard to keep the carbon in line though. Maybe an open mold would be better?
Thanks,
Jerry Barth
