In Poland the lightest boat powered by photovoltaic panels was created. It is an unusual combination of sport with renewable energy sources. The hull of the boat weighs only 12 kg and is built according to infusion technology. The boat with all equipment weighs 224.5 kg and is extremely light. Boats constructed in this way are ideal for swimming on canals, lakes and rivers. It is quiet and ecologically, because the solar-powered engine practically does not emit any sounds and does not seem to pollute the environment.
