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.
