interesting. For us it would work much better in a conventional pole to mast-head hoist. A parafoil on end. Two skins held together with baffles and gauze at the leading edge. I suppose it would be half the actual area in size ( 10.5 sqm ) as it would be essentially two spinnakers. Ummmm....

I saw one of these on a HOD 35 yacht 2.5 years ago.  Appeared to work.
If as intended it gives greater lift forward you would never have to worry about letting off the T foil at the windward mark. I'm not sure how it would work in an asymmetric though.

it's good to see above that Tom is being very agreeable to day.  Smiley

That bit's easy. Its the coming down again that's troublesome. Trust me on this.
