The vessel is 31 meter (192 feet) long, 15 meter (50 feet) wide and 7.5 meter (24.5 feet) high. The solar units cover an area of 500 square meters (5,382 square feet). The world’s largest solar-powered boat built by Knierim Yachtbau revealed its futuristic shape for the first time during an official ceremony held at the HDW shipyard in Kiel. The next milestone for the entire PlanetSolar team will be the launching of the boat. This major premiering event is scheduled in the upcoming weeks in Kiel. It is planned to take the yacht on an around the world journey in 2011. (AP Photo/Heribert Proepper)
