Silent Yacht manufactur electric and solar powered sea-going yachts at their associate shipyards in Italy and China. They would be launching the Silent 55 in Sep 2019 at Cannes Yachting Fesitval. The Silent 55 is built by Mazarin German Yachts at their Chinese facility.  The Silent 55 is a 56 feet electric-battery catamaran. This yacht will cost approximately Euros 1.5 Million. The company claims that the Silent 55 has a much lower carbon footprint as well as operating costs, thanks to its high efficiency solar panels and Lithium batteries. Because it is battery powered and these batteries are charged by the solar panels, theoretically the yacht has an unlimited range till the sun is out. The batteries have enough juice to power the windlass, airconditioning, lighting and powered swimming platform at night. The propulsion motors of Silent 55 are; umm; silent with low vibrations and are virtually maintenance free.
