My goal was to build an electrically-propelled power boat with a comfortable cabin that could be easily towed behind a modest car. It also had to be relatively simple to build, and fit in a standard garage during construction. Bernd Kohler’s Eco 55 design looked ideal. Building began in late 2019. Construction is stringer and frame with Okoume ply, and epoxy/fiberglass exterior. The electric outboard is from the Czech Republic and is powered by four 24 volts, 75 amp-hour, Lithium-Ion batteries wired as a 48-volt bank. Charging is via two solar panels and shore power. The cabin has a double berth, two hanging lockers, additional storage, a composting head, and a small galley unit with a propane stove and sink. The cockpit has plenty of room for relaxed seating.
