Sturmboot

Already at the beginning of the 20th century, the "Wiener Dampfsturm Yacht from 1907" delighted visitors to the Prater. There are only 3 of these systems in the world, which is why it was a matter of great concern to the operators of the Prater to bring them back.
The two boats, powered by electricity, rock up and down, back and forth, and when they opened it was considered an absolute thrill ride.
