Spend All Day On The Lake

Solar vehicles are getting more and more common as the price of solar panels comes down, and the availability of motors and controllers for all of these vehicles rises. Making a solar-electric bike from a kit is one thing, but this solar-powered boat is a master class in hacking at all levels, from the solar drive train to the pontoons, and even the anchor.

[J Mantzel] has many videos about his boat on his channel, and watching them all will likely leave you wanting to build your own. He builds almost everything on his boat from scratch from things he has lying around. For example, the anchor was hand-built from fiberglass and then filled with concrete, and his steering system is a semi-complex system of ropes, pulleys, and shafts. Most of the boat’s shell was hand-built from fiberglass as well, and everything that can be repurposed is saved for later use.

The ten panels, batteries, inverter, and other miscellaneous part of the system were about half of the cost of the whole vessel, but he reports that he also uses the boat as a backup power source for his house, and can use the system to run other things like an electric chainsaw for example. He also uses the boat for camping and construction, and without having to worry about fuel it has been very useful to him.

If you get into the videos on the channel, you’ll find that this isn’t his only solar-powered boat. He recently completed a solar speedboat as well with a custom-built propeller that can really move across the water. His videos are apparently very popular as well, since they have been linked to repeatedly by readers in some of the recent solar vehicle write-ups we’ve published.
