Maughan,
technically, kickup daggers are not too hard to do. There has been made some prototypes for the Tornado. The downside is that you need gaskets to cover the bottom of the well as the boards need room to rotate aft..
Look at this:
http://personal.inet.fi/private/muu/boards.htmThe mechanism can be refined a lot so it's hidden in the hull, or look for some other ideas further down on the page. Knowing a certain designers ability to think "out of the box", there might be something completely different in the works.
PS: Browsing trough Reino Uralas site is well worth, he has done lots of interesting stuff. Last was a VPP study of when to go double trapezeing downwind with the spi on a Tornado..
