I really like the 2009 setup other than
all the lines going from the back of the sail to the blocks. I wonder if
there might be a better way to keep all the wishbones inline. Maybe if
you could somehow torque the top wishbone, the rest should follow. That
would also let you put “washout” on the sail like on an airplane
wing so you could depower the sail somewhat without having to reef. I
think to torque the top wishbone you could have some kind of control arm on top
of the mast that engages the top wishbone when it is all the way up. Do
you guys think that this would work?

Hi Mike,
The reason to have these wishbones on the first place is to
be sure of a good sail shape.
That means they have to be rigid. Otherwise in a gust your
sailshape would be reduced to some sort of spinnaker.
So the stiffnes of the wishbones keeps the sail shape you
need to translate the gust into speed instead of drag.
