Hmmm, weld them back-to-back and it will look like an aluminum viking boat!

Seriously, I can't offer any advice, but hope you will post pics if this goes forward.

I've added width by doing this but haven't tried lengthening. It's very time consuming and way you cut it (no punn intended). From the measurements I did adding width to a flat bottom I'll assume that you'll have to fare the two sections together. I think you'll find that as you progress down the length of the hull that the width measurements are going to vary a lot which will create a "step" in the hull. Good luck!

Reminds me of my old race car chassis builder mentor saying: "It's easier to add it OFF than add it ON". TexasJim

In my younger days, remember seeing homemade boats out of plywood, or steel construction. One of the most interesting was a steel boat, made by welding 2 40 ford hoods back to back. It looked like a steel canoe.

If you are trying to add 10' to the boat, that might have some structural issues, where the boat wants to "fold" in the middle. You want super-strong, structural rails and keel to support that if you attempt.

A lot easier to add 2-4' to the back.
