I would love to see this too. Its a great idea I think...cloud forming over my head. The pitch-pole physics may be better with some out rigger (river kyak, pregnant surfboard like) pontoon wings, Which will also shift the cog lower and rearward. The wings will give you your wider beam, and if you make them foldable or easily removable- you can still trailer it. Maybe could rig it with stock size wing tramps. The added weight would require a very lightweight crew though to me most effective. You probably would want the out riggers to be about 12" or so off the water, or enough to be still able to balance on one hull, (maybe even easier to get one hull out of the water) but the pontoons should be like training wheels, rocked back, if you go too far.... (gulp) made for it not to grab the water, but will skim off it; to look good on paper maybe
to work like a sea plane pontoon and not a submarine. The prototype should be easily adjustable if you need to shift them up, down, forward, back, angle.
