Torqeedo’s Customized Solutions team converted the 138-year-old Kaiser Friedrich to electric power, saving over 150 liters of diesel per operating hour.
The Kaiser Friedrich, a twin-screw steamship, plied Berlin’s waters for almost 80 years before it was decommissioned in 1967 and converted into offices and residential space. In 1986, the German Museum of Technology purchased the 100-ton boat and restored it to its original appearance.
Starting on 13 May, Berliners and visitors to the “Athens on the Spree” can enjoy an eco-friendly city tour on board this legendary passenger vessel. At night, the city’s most famous boat transforms into a floating beer garden during the 3.5-hour Old Berlin Beer Evening. Online booking is available at
“The Kaiser Friedrich is a longtime maritime landmark of the city,” said Mr. Marhold. “And now it is also a symbol of transformation towards the mobility of the future. And what a wonderful future for Berlin’s oldest passenger vessel, which can now once again welcome passengers to celebrate life with them while enjoying breathtaking views of our beautiful city.”
