some photos of testing tryouts inovation on 2010 vapor prototype:
Important: This is only test prototype, not final look of vapor
I am very shure that this don't be vapor 2010 look
cheerz 
mmmmmmmm as i see it, it could be painful re-theading your adjustable outhaul everytime you rig up as you would have to take off the tail peice of your boom to get it through the sail. [}:)]
Looks wicked though
Hard to see how the foot is cut in these photos, but I can see how this could be a problem if the foot is not cut quite short...

Yep, A.R.T tried this years ago, A.R.T sails also had a normal rear eyelet position.
Years ago had some of those A.R.T sails & still have the rear end boom fittings.
Using the A.R.T sails with the boom connected to the inner eyelet similar to Gaastra position in the photo didn't seem to work . The sail shape was unstable, lack power/ drive, unable to sail upwind, ended up only using the normal boom rear eyelet position.
Maybe Gaastra have made the A.R.T concept stable & it actually works now?
yes there is a zip, but excuse me, I forgot to wrote that this is not
final look of vapor. This is only some prototype version for testing purpose only.
I don't think that this will be out. For that we need to wait for official
look on gaastra site for 2010.
this is i think real look of gaastra vapor 2010
no boom inside, no zip, I suppose that idea don't work at all
as ICE said....
This prototype for big sizes is currently being tested in Sylt after Santa Pola with Dagan.

"The latest version before final production launch will be decided after a final test session in Marseille with Pritchard, Bordes, Williams and Dagan."

Vapor 2010 :
That is definately not the 2010 model, we have already tested the 2010 in Tarifa in July. Vapor 2010 goes into production late November -December and should be in Aus early Jan.
thanks David
If you put a cutout to a sail i think the skin tension will change dramatically.
So you will have to design the sail all over. I have heard that you will loose stability with cutouts. These cutouts are often done only because of demand from the markets. Not because it would give you some kind of edge.
