Wow That will set the speculation on fire! Thanks @Boybland

Not that I have seen and I am always looking for details of the twin skin setup.

Can you comment on the photos above which is where I am coming from on the twin booms? there are some interesting ideas how shape-able booms might be built to control the bottom and hence the greater part of the twin skin. I believe this shape-able twin skin is the secret to it being more powerful at low speed and less drag at high speed.

Wow yes that gripper could be adapted to make a very controllable boom, but does it have the vertical strength?

I like the idea of air booms if they are vertically strong using some vertical titanium sheet and something stopping twist OR Twin air booms?

two booms ^ Two flexible booms It's is a push to think they are still using this setup but I think they are.

Looks fairly smooth curve on the inner skin. But could be achieved as you say. They are allowed a metre of "mechanism" at the bottom of the sail (must be pretty transparent?)

@17mika Looking something like this, skins thin lines boom thick line?

Did the NYYC buy through S&S the ETNZ design package to get the info on the defender?

@Stingray I can answer that for you. I would love to tell Jimmy to "move over" again !!

I am with @Monkey If you need me to I will start another ACRugby like thread. I find this military discussion worth having but not here please.

Does ETNZ have two bendable booms one for each skin? Looking at the gap between skins of the Mule there is a big gap at boom level at the widest part of the wing.

To get the wing shape would they have two camberable booms? The lee one bent more then the windward one?

@uflux surely you can't be serious that there will be no races under 12 knots?

Will they go soft boom or/and Seal the main to the deck? do the sides of the hull give a clue?
