You probably don't have time to wade thru the rest of this nonsense, so here's the skinny:

I intend to scratch build an ultra-light epoxyed plywood pontoon boat with a deck area of about 7 ' by 14' on 16 ' pontoons.
The craft will be powered by two 24V DC motors. The power will come from eight 12V Deep cycle marine (lead/acid) batteries that will be charged by solar panels and small vertical axis wind turbines.
The system will be split into two separate, isolated units
with one motor, two pairs of batteries, 2 wind turbines and solar array for each side.

The craft itself is still on the drawing board, there's some details left to work out but they're minor.
The current design displaces over 2200 pounds with only a 12" draught.

The plan is to take this boat from as far up the Mississippi as she can navigate down to New Orleans,
relying only on the solar and wind generated electricity she can create on board.

I'm still at it.

I'd be so much better off drawing in AutoCad then Adobe Illustrator,
but that's all I've got on this iMac.
The hull is re-drawn. It turns out I didn't leave enough room in the
stern for the motors. I'm working on the hardware for the tillers now.

I'd like to set up my control console dead center on the deck,
but that's the only place I can sling my hammock.
If I locate it aft, it simplifies the tiller and shortens the wiring for the
controls, but a console will eat up valuable deck space no matter where I put it.
...when your whole world is going to be contained in 98 square feet for a couple of months, you don't want to give any up. I may end up add 2 feet to the deck and pontoons anyway.

I got a chance to exchange emails with an incredibly nice gentleman
from up in Canada who's scratch-built a really neat electric powered canal boat. It's a really elegant little craft. Here's an article on it:
Greenhorn I
It's a radically different craft from what I intend to build, but he was
very helpful regarding motors and I may pick his brain again later on
when it comes to hooking up the solar array and turbines.

I also had a guy link me to some ESC's that are designed for an electric motor scooter. They seem to do everything I need and at $40 each they're a way better deal then the $300 industrial duty jobs I was looking at.
Slow progress is better then no progress right?
