Transatlantic Passagemaking, via Solar Power

When sun21 arrived in Martinique’s harbor on February 2, 2007, she became the first motorized vessel to cross the Atlantic under solar power exclusively; her 52-day, 3,500-NM trip began at Porto Sherry in Chipiona, Spain. sun21 is the brainchild of Mark Wüst, a Swiss shipbuilder whose goal was to prove that solar-powered technology was capable of providing sufficient energy for passagemaking. After extensive research a ship was built, and its maiden voyage was along the Rhine River from Basel, Switzerland, to Rotterdam, Netherlands.

The 45-foot sun21’s solar power is collected via 48, 2'x5' photovoltaic panels on her roof that power twin 8-kW Lemco lightweight, low-voltage D.C. motors. During the 52-day trip, sun21 harvested 2,000-kWh of solar energy; the crew estimated that a similar-size and powered diesel yacht would’ve burned more than $4,700 of fuel during the same trip.

The sun21 is scheduled to arrive in New York City’s North Cove Marina on May 8th; stay tuned as PMY will certainly cover her arrival. For more information on the sun21, or to read the captain's log documenting the journey, go to the sun21 Web site.
