Mantzel worked with the Wow!
Mantzel gets pretty good speed even on a cloudy afternoon;
Mantzel had to extend the length of the motor to reach the water.
Taking what he learned, Mantzel built a larger pontoon boat with many clever innovations.
So Mantzel used a 3D printer and laser cutter to create prototypes,
and often shot video to demonstrate how they worked.
This time, instead of starting with plywood, Mantzel formed his own molds to create fiberglass pontoons
and a frame for his boat.
In addition, Mantzel would like to use the whole roof as a sail
to give him the option of moving under wind power.
For the motor, Mantzel hacked together a broken outboard motor
purchased for $20 and a 24V Leeson DC electric motor, rated for 1.5 HP.
Mantzel is still working on the mechanism to tilt
the solar panels to capture maximum sun, or to use as a sail if there is no sun and good wind.
