These solar electric boats, requiring no fuel and little maintenance, demonstrate that 100% solar powered marine transportation is practical. Sol, (2011) a 25 foot launch, operates on an Adirondack lake where there is no road and no electricity. Solar Sal, 40 foot and named after the old Erie Canal song, has been cruising the Hudson River and Erie Canal for three boating seasons transporting people and cargo. Neither has ever been plugged into shore power.
