The problem I could see by extending a twin is that the wing needs to have about 30% of its area behind the rear axle. If the wing is too far forward then you can't steer because the side pressures create a lee ward helm.  If you could make some thing similar but slightly  smaller version of what Phil Rothrock or Ben Gooch use  it would be perfect. One of the requirements of wings is a nice big stable platform that has positive control for the wing as well as the right placement of the wing to balance the boat.

What about adding a front spring board and new rear axel to get the 18.8' x 16'? It would be real easy for me to make up the mounting plates for both of them. Or would it be easier to go with a smaller wing?

The wings require a large platform for stability. The previous boat that it went on was about 350lbs and had a footprint of 18.5' long and 16' wide plus the wheels.
I'm afraid to get that wing to work right you are going to have to start from scratch  on a new fuselage .

Is it possible to put the wing you sent me on the Manta Twin that I have. If so what would it take. Remenber I have a CNC Machine shop and can do anything.
