I've been tinkering with this project on and off for a couple years now. Testing different setups and I think I'm near my final product. I felt the most efficient hull to begin with was a Catamaran so when I found this old 1963 Shark I saved it from the landfill and started.
I planned to do an outboard conversion but that wasn't as easy as I thought so I also tried single and dual trolling motors. Batteries and solar panels were laid out wherever I could fit for testing.
Eventually I built the solar roof, 12 - One hundred watt panels
So today, after many trials and tribulations I will start to finish it. The setup, 1200 watts solar, three 6 volt batteries in series for 18 volts and 2 - Minn Kota 74# trolling motors with aftermarket high pitch props.
Speed will be about 5 to 6 mph and can pretty much run all day on a average sunny day.
