Not enough draft in upper sections

Actually, no. I'm used to lightweight dinghy where the max depth of
the chord is only 12%. But in this case, the issue isn't bagginess
at all. It is the simple fact that a well cut sail will be
relatively deeper in the upper sections.

In any event, in light air, a big round section with a relatively
flat entry will keep attached flow and build up much more power
than a draft forward conventional airfoil shape.




Leach closed.

No it isn't. You cant tell the twist from that camer angle

I can see the topping lift, whih is presumably straight, and the
distance from the battens to the topping lift does not appear to
increase towards the middle of the sail. Also, it appears (could be
due to camera angle) that all the battens are at the same angle.

Looking closely, I can see what might be leach ribbons flowing.
That's a good sign.




Why do you have a backstay antennae and no wire to it? Is the
wire lead up the mast and to the antennae at the top?

Well spotted. The wire is off.

OK, that's allowed
