Mike,
The Junk rig guys are making some good progress
on soft wings. There are two or three different variants, you can look at them
in the members section of the Junk Rig Association. They’re also using alu
light poles for masts. It’s well worth paying the $15 or so a year to be
a member, their magazine is very good as well.

They have been testing what they are calling the V14 sail on a T29
trimaran with what appears to be a 12m stayed mast.
The sail is not yet optimized, particularly for reaching, but they did
say they can point ten degrees higher than a Farr 40, while moving faster,
tacking through 60-65 degrees.
And that's on a 9 meter 1200 kg trimaran with an upwind SA/D of 58, not
a 12 meter 700 kg proa with an upwind SA/D of 70 to 90 (depends upon the mast)!
It's exciting to see the tests with a larger sail. The T29 might
only have a 12 meter mast (estimating from photos), compared to BL's 18+
meters, but that's still a more useful example than the earlier tests with the
smaller boat.
My dream of someone else doing all the hard work of developing a
reefable wing sail that lets me use a fixed mast is slowly coming true.
