Spitz in the Wachau
Stopping in Mitteransdorf just before the point where the Danube makes its turn Northward, we looked across the water to the town of Spitz. According to Wikipedia: "The ferry across the Danube here is interesting in that it has no motor or sail: it is powered by rudder set against the river current, anchored to a cable above the river. The ferry carries passengers, bicycles, motorcycles, and automobiles."
