Cool picture.
We experimented with this idea a while back. The VP programs said that a single .21 would produce a better P/W ratio.
The other problem was that the wide tub created lift like a tunnel hull and would be almost impossible to keep on the water at anything over 50 MPH.
But who knows untill you actually try it. The programs have been wrong before.
It sure would be neat to hear those little .12's screaming away in harmony across the pond.
