G'day,
 
The calculated weight is not exact yet, but the wing weight will not be a whole lot more than that of a ballestron.  It is smaller in area, but much more efficient.
 
The central rig is to allow the boat to go alongside walls, other boats etc without having to worry about the rig hitting things.  The rig is designed to weathercock when not in use, so must have room to rotate.  As it is unstayed, there are only small downward loads on the bridgedeck, so it should not be too hard to design for these. 
 
We started a prototype rig for Elementarry, but decided that the really interesting things would not scale. 
 
JT is on the list, and may want to tell you more. 
 
Regards,
 
Rob

Hi Mark,

Can you tell us more about JT's boat? eg What is its calculated
weight?, why a central rig? is a prototype being built?

Thanks,
