Vlad,
I also believe this, and once I got this fine tuned, this folding catamaran system will become the standard ufc boat.

And this will be a fast boat, someday. maybe not in the river sections but in open waters.

It still has years of development to go though, but the first version will/could be ready soon. But like you, I'm on a budget so I can't just jump into what I think the best design is gonna be.

Like another poster said, look around for an older A-class boat and modify that, though this kind of shopping around will take time and I'm not exactly in the middle of the fleet if you know what I mean. south padre is a great place, but it's far removed from much!
