Locks ~ European River system

We are sailing from Amsterdam to Budapest ~ along this route, we must use 68 locks., to climb over.....and drop down from, the European Watershed, which is at 1340 feet above sea level.
Today’s Blip shows us sailing into the Randersacker Lock, in Germany, which is lock number 22 of the 68.
We are sailing throughout the day and night; sometimes we passengers are going off on excursions, while the ship continues sailing onwards.
Tomorrow we will leave the River Main, and join the Rhine-Main-Danube Canal......and from there, we will join the River Danube and sail on to Vienna, then to our final destination of Budapest.
