You guys may add me to the listing as I'm still working on it. Thanks to Gareth (Grob) I have a nice 3D drawing of it as well, although a few modifications need to be made before the pics will be publicized on this forum.

I too use a non rotating mast, but it is also unstayed. Interestingly my rig is somewhat a cross between the rig by Gareth and Chris.

I too intend to make it available to homebuilders.

Maybe it is wise for the interested parties (designers) to get into contact and finalize the F12 specs between us.


As Gareth is certain right, the F12 is not dead yet.
