Six Hours, Four Locks | Rediscovering the Neckar Aboard the WILHELMA

A River Looks Different from the Water

Some rivers become so familiar that we stop looking at them.

We cross them by bridge, follow them by road and pass them by train. The Neckar is part of everyday life in Baden-Württemberg, yet most of the time I encounter it only briefly—from above, from the side, or through a window.

On 11 October 2026, I boarded the passenger vessel WILHELMA in Stuttgart and spent six hours travelling along the Neckar toward Marbach and back.

I had expected a pleasant Sunday cruise. Instead, I barely sat down.

I kept returning to the blue bow, watching the riverbanks change. I watched the vessel enter locks and move with the changing water level. Later, I stepped into the wheelhouse and watched the captain navigate a vessel built in 1962 through a river that has itself been repeatedly reshaped by engineering.

By the end of the journey, the Neckar no longer appeared simply as part of the landscape.

It had become a working system of navigation, infrastructure, industry and everyday life.

A Ship That Stayed on the Neckar

The WILHELMA was built in 1962 by Wilhelm Schmidt & Söhne in Oberkassel for the Berta Epple shipping company.

She belonged to a generation of passenger vessels that once formed part of a larger world of excursion shipping on the Neckar. Over the decades, sister vessels were sold, moved to other waterways or disappeared from service.

The WILHELMA stayed.

More than sixty years later, she still operates on the Neckar and is described by her present operator as the flagship of the fleet. At 37.20 metres long and 7.20 metres wide, she contains indoor passenger areas, a Käpt’ns Lounge and two outdoor decks.

Standing at her blue bow, however, those specifications mattered less than the simple fact that this was not a historic vessel preserved motionless on shore.

She was still working.

The wheelhouse made that continuity especially visible. Physical switches, control levers and older instruments remain in use, while electronic displays, radio equipment and modern navigation technology have been added around them.

The vessel has not survived by remaining technologically unchanged. Different periods have accumulated within the same working ship.

Captain Stefan Appl told me that he had worked in Berlin for around ten years before returning to Baden-Württemberg four months earlier. Talking with him also made clear that navigating a passenger vessel involves much more than simply steering. Water levels, the fairway, weather, vessel condition and locks all enter into the decisions made from the wheelhouse.

Outside the wheelhouse, another world existed at the same time. Passengers ate breakfast, families talked at their tables, children moved around the vessel, and a group of fifty-three people from Winnenden travelled together.

For them, it was a Sunday excursion.

For the captain, kitchen and service staff, it was a working day.

The same vessel contained both worlds.

Four Locks, Four Changes of Level

The most memorable part of the journey was not a monument or a particularly picturesque stretch of river.

It was the locks.

Travelling from Stuttgart toward Marbach, the WILHELMA passed four of them: Hofen, Aldingen, Poppenweiler and Marbach.

Each time, the open river narrowed. The blue bow entered a long chamber between high concrete walls. The vessel stopped. The gate closed.

Then the water began to change.

A lock does not lift a ship mechanically. Instead, water is admitted to or released from the chamber until its level corresponds to the next section of the river. The vessel rises or falls with the water before the opposite gate opens and the journey continues.

The principle is simple on paper. Experiencing it aboard a ship is different.

The concrete walls become a measuring scale around the body. What had been an abstract statement—locks allow vessels to overcome differences in water level—becomes something physically experienced.

The four locks also differ in scale. Hofen has a stated fall of approximately 6.8 metres, Aldingen 3.6 metres, Poppenweiler 7.0 metres and Marbach 6.0 metres. Together, those stated differences amount to 23.4 metres across four engineering nodes.

The number itself is not the point.

What matters is that a river that appears continuous from the bank is actually organised into sections of different water levels. Locks connect those sections and make continuous navigation possible.

Watching from the bow, I began to understand the Neckar not simply as flowing water, but as a navigable river assembled through a sequence of hydraulic interventions.

A River That Works

From the deck, another Baden-Württemberg appeared.

There were vineyards, wooded riverbanks and settlements. There were also bridges, locks, industrial facilities, energy infrastructure and urban spaces.

They did not appear separately.

They followed one another.

A vineyard might rise above the river, followed by infrastructure or an industrial site. Residential areas appeared beside transport connections. Near Hofen, water was simultaneously part of navigation infrastructure and a landscape of recreation around the Max-Eyth-See.

Around Poppenweiler, the perspective changed again. From the river, vineyards could be seen climbing the slopes above the Neckar. The relationship between water, topography, cultivation and settlement became much easier to read than it is from a road.

And then industry returned.

That contrast raises an interesting question: if a river carries navigation, energy, industry, agriculture, settlement and recreation at the same time, why should we expect it to remain picturesque?

The Neckar is not scenery arranged for visitors.

It is a working river.

Its industrial facilities do not exist outside the story of the river any more than its vineyards do. Nature, technology, industry, culture and everyday life occupy the same corridor.

Seen from the WILHELMA, Baden-Württemberg therefore ceased to resemble a postcard.

It became a region in motion.

If I Sit Down, I Might Miss Something

During those six hours, I barely sat down.

I watched the banks from the blue bow, stood on deck as the WILHELMA passed through locks, and entered the wheelhouse to watch a sixty-four-year-old passenger vessel continue doing the work for which she had been built.

Perhaps six hours sounds long for a river cruise.

For me, it passed surprisingly quickly.

Once I began to understand what I was looking at, even waiting became interesting. A lock was no longer simply a delay. An industrial facility was no longer something interrupting the landscape. A bridge was no longer merely a way to cross the river.

Everything began to reveal relationships.

We know Baden-Württemberg from its roads and railways, its cities, museums and tourist destinations.

The Neckar offers another way of reading the same place.

From the water, one can experience four locks, look upward toward vineyards, pass industry and settlements, observe a passenger vessel at work and discover that the river crossed in a few seconds by bridge has its own infrastructure, rhythms and working life.

Near the end of the return journey, the WILHELMA entered another lock.

The blue bow waited between the high walls. The water changed level. The gate opened, and the vessel pointed toward the river once again.

Only then did I realise that the day was almost over.

I still had not really sat down.

Not because there was nowhere to sit.

But because I kept thinking:

If I sit down, I might miss something.

And when the WILHELMA finally returned to the landing stage, I discovered that I was not quite ready to leave.

Across Civilizations

Why Must a River Be Romantic?

King Kaolie stood at the bow, looking first at the vineyards and then toward the industrial buildings in the distance.

“The scenery along this river keeps changing,” he said.

“Some people like the vineyards,” I replied, “but dislike the locks and factories. They expect a river cruise to be more romantic.”

Lord Chunshen Huang Xie laughed.

“If the Yangtze heard that,” he said, “it might ask a question of its own: Why must a river be romantic?”

King Kaolie looked at him.

“Isn’t a river simply a river?”

Huang Xie nodded.

“Some people sail on it. Some cultivate the land beside it. Some build cities and transport goods along it. Others come simply to enjoy the view.”

I looked toward the banks of the Neckar.

“That is what I gradually realised. The vineyards are not more real than the industrial facilities. Both belong to the river.”

The king turned toward me.

“Then what were you looking at for six hours?”

I thought for a moment.

“At how one river can allow so many different forms of life to happen at the same time.”

Huang Xie looked toward the blue bow.

“That,” he said, “sounds rather like the Yangtze.”

A river is never only scenery.
It carries ships, but it also carries life.
People build their worlds along rivers,
and rivers, in turn, shape the worlds people build.
