What if you combine a skipjack type hull with a seawolf pumpjet, a cutdown or Alfa type sail, and maybe a X-tail, wonder how she would perform?

My friend, Kevin Rimrodt, and I did a Y-tail conversion of a 1/96 SKIPJACK, as well as a radically new type of sail. That was about 20 years ago -- we've yet to get it into the water.

Kevin came up with the idea that too limit vortex shedding contact with the sail (which occurs near the boundary layer) -- a component of 'snap role' -- he came up with a sail design where the masts and bridge were up high in a sort of 'gondola' which connected to the hull with a very narrow, and short of cord, connecting dorsal.
