Chain-boat navigation or chain-ship navigation is a little-known chapter in the history of shipping on European rivers. From around the middle of the 19th century, vessels called chain boats were used to haul strings of barges

Historical development

Early technical developments before the 19th century

The transportation of goods by river in the early days of the chain boat was restricted to wooden ships without their own on-board power. When travelling downstream, boats were either simply propelled along by the current or sails would employ wind power. To move upriver, men or draught animals on towpaths were used to haul the boats on long ropes. In shallow waters boats could also be propelled upstream by long poles. Where towing from a towpath on the riverbank was not possible, a method known as

was used. These sections of river could be negotiated by anchoring a rope ahead of the boat and then using the crew to haul it upstream.Sigbert Zesewitz, Helmut Düntzsch, Theodor Grötschel: ''Kettenschiffahrt''. VEB Verlag Technik, Berlin, 1987, Schiffstauerei Mariano 1438

In an illuminated manuscript dating to 1438, the Italian engineer, Jacopo Mariano, illustrated the fundamental concept on which chain boat navigation was subsequently based. The boat is pulling itself upstream on a cable laid along the river. The rope is wrapped around a central shaft driven by two, side-mounted water wheels (see upper diagram). Behind the river craft is a small boat-like object being pulled by the current, that is holding the cable taut and thus ensuring the necessary friction on the shaft.Feldhaus, Franz M.: ''Die Technik der Vorzeit, der geschichtlichen Zeit und der Naturvölker, Ein Handbuch für Archäologen und Historiker, Museen und Sammler, Kunsthändler und Antiquare''.

The smaller boat, which is travelling downstream, is moving very fast, driven by the large water sails on either side and is thereby hauling the larger boat upstream against the current. The large barge in the picture has two, side-mounted water wheels that coil up the cable and increase its speed further. It is not, however, recorded whether the system was used in practice. In 1723 Paul Jacob Marperger, who later became the Electoral Saxon ''Kommerzienrat'' described a proposal by mathematics professor, Nicolaus Molwitz from

, to use mechanical assistance in order to cope with the fast currents below Magdeburg's bridges. At that time, 50 men were needed to negotiate this section of the river. The idea was to build a 'machine' with two horizontal shafts, the towing cable being turned around the front shaft in such a way that it was continuously being unwound from it again and onto the rear shaft. According to Marperger, with the additional use of levers it should have been possible for five or six men to successfully effect the passage of the boat. At the same time, however, he stressed that the machine was "produced" but "never taken into use". From his description, elements of this basic principle seem to be similar to those subsequently used later in building chain boats. This section of river was later to become the starting point for the first chain boats in Germany. Seilschiff nach Marschall von Sachsen

The first practical attempts to use a cable boat were in 1732 at the instigation of Marshal Maurice of Saxony, then in French service. These took place on the

in the vicinity of Strasbourg. Three pairs of cylinders of various diameters were arranged on a horizontal shaft and driven by two horses. Depending on the required force, the rope was hauled in by winding it round one of the pairs of cylinders whilst the other two pairs coasted. The variable ratio allowed for a better utilization of force. Compared with the towing from the land this system could move double the load for the same number of draught horses per craft.Cpt. C.V.

Experiments in the first half of the 19th century

After 1820 several inventors in France worked separately, but simultaneously, on the technical implementation of boats that could be moved by cables or chains. These included engineers, Tourasse and Courteaut, who conducted experiments on the

meant that, for the first time, a motor was now available to power ships independently of wind and wave. The power of the first steam engines was, however, relatively low whilst, at the same time, they were very heavy. So attempts were made to utilize its power in the most effective way to move ships. Somewhat later the two engineers, Tourasse and Courteaut, undertook trials on the Rhone between Givors and

. The latter hauled itself upriver on the rope, passing it to the drum on the escort ship as it went. During this process a second escort ship hurried upstream in order to anchor a second rope and thus save waiting time. Vinochon de Quémont carried out trials on the River Seine in which the rope was replaced with a chain. The results of the first trials may be read in the 1866 Yearbook of Inventions: ''Although all these reviousattempts did not use a continuous chain, rather the tow chain always had to be taken forward by a boat before the ship could be set in motion, the results appeared to be so pleasing that by 1825 under the leadership of Edouard de Rigny a company was formed based on these systems in order to negotiate the

.'' The introduction of the ''entreprise de remorquage'' failed, however, due to faulty design. The chain steamer, ''La Dauphine'', was not built exactly to the Tourasse's specification.

In: ''Centralblatt der Bauverwaltung'', Berlin, 1881, pages 189–191 Moreover, the company's capital was insufficient. In 1826, M.F. Bourdon tested a variant with two steam ships.

However, a lot of time was lost during the anchoring manoeuvre. From the time of those early attempts in the first half of the 19th century, chain boat technology improved steadily and the first successful use of chain boats in France took place. After that, other French rivers and canals were also provided with chains. In Germany, chains were laid in the

, especially on rivers with strong currents. Compared with the hitherto standard towing method, a chain boat could haul many more and much larger barges. The possible load of a single barge rose five times in just a few years. In addition, the chain boat transport was much faster and cheaper. The number of trips a boat could make increased, for example, on the Elbe almost three times.Erich Pleißner: "Konzentration der Güterschiffahrt auf der Elbe".

Siemenroth & Troschel, Berlin, 1899, pp. 57–58 Through the use of the steam engine it was now possible, for the first time, to meet the rising demand for the transport capacity driven by increasing industrialization in the second half of the 19th and first half of the 20th century. Chain boat navigation gave sailors and their barges the opportunity to compete against increasing competition from the railways. Before the introduction of chain boats,

s were already working as tugs and cargo boats on some stretches of river, but they did not hail a breakthrough in mass transport. Due to its dependence on the water level of the river and on market economic interests, the steamer could not guarantee a regular service. Not until regular services with fast connections, as well as the guaranteed, low transportation costs of the chain boats, could river barge transportation begin to be competitive. With the development and growth in the use of new forms of power, such as the screw propeller and diesel engine in the first half of the 20th century, self-propelled vessels increasingly superseded the chain boat. The development of river systems and competition from road and rail further reduced the profitability of the chain boat industry that was designed for continuous towing. In time, the use of chain boats became restricted to a few particularly difficult sections of river.

Distribution in Europe

France

In 1839, the first technically and economically successful chain steamer, ''Hercule'', was built and on a roughly stretch of fast-flowing water on the River Seine within the city of Paris.J. Fölsche: " Kettenschiffahrt auf der Elbe und auf der Seine". In: ''Deutsche Bauzeitung'' 1 (1867), pp. 306–307 and pp. 314–316 It was on this very same section of the river that de Rigny had failed a few years earlier due to technical difficulties. Starting from Paris in 1854, chain boat services spread upstream to the town of Montereau at the confluence with the

of the Seine offered ideal conditions for chain boats. The river was uniformly deep, had a relatively steep gradient and its bed was sandy and even. By contrast, rivers whose source lay in the Alpine region, were less suitable. This meant that, especially when the rivers were in spate that they carried large amounts of sand with them. In trials carried out on the Rhone, it was found that the chain frequently became buried by sand and stones. Trials on the

also failed and were relatively quickly terminated. The chain boats also provided river transportation on the canals in France, as well as on the rivers. Tunnels on the highest level of these canals were very long and electrically driven chain boats were used to tow boats through them. Due to the lack of ventilation in the tunnel systems, electrically operated chain boats continued to be used even after the introduction of self-propelled motor vessels.

and the canal's confluence with the Rupel. Unlike chain boats in France and Germany, chain boats in Belgium used the von Bouquié system, whereby the chain was not led down the centre line of the ship, but simply over a chain wheel at the side of the ship. The chain wheel was fitted with teeth to prevent the chain slipping. Every day about five chain boats operated hauled in each direction, each hauling a chain of 6 to 12 barges.

The first two steamships on the Elbe were wide and long and fitted with engines generating about motorized, and hauled four barges of up to 250 tons. By 1871, the chain had already been extended from

. There were ten chain ships in use. The chain increasingly broke (on average once per trip) which was the reason why the chain boats were converted in 1890 into tugboats. In 1891, chain boat services were established between Regensburg and Hofkirchen (). In 1896, chain boat services between Vienna and Ybbs ceased and, in 1906, services between Regensburg and Hofkirchen were also terminated. Due to the strong current on the Danube, chain boats could not use the chain when travelling downstream. They therefore had to have large paddle wheels on their sides, as additional means of propulsion, generating .

city locks. For many years, horses had been used to tow barges along this , very winding and relatively fast flowing section of the river. On 12 November 1868, the owner of the Bromberg Haulage Company (''Bromberger Treibercomptoir''), responsible for towing, applied for a licence for the introduction of a chain boat operation on the lower Brahe to the council in Bromberg. The concession granted on 3 June 1869 was limited to a period of 25 years and essentially corresponded to the Prussian regulations in force on the Elbe. Shortly thereafter, in the summer of 1869, the first trail run began using a chain steamer built by ''Maschinenfabrik Buckau''. The operation had to be terminated in the autumn, however, as the boat could not deliver the required performance and speed. A replacement boat with sufficient power was introduced in summer 1870. Nevertheless, only one or two trips could be made per day. It was not until the construction of a short cut on the most critical stretch in March 1871, and the acquisition of a second chain boat in spring 1872, that significant number of timber rafts could be hauled by chain boats. One steamboat gathered the rafts near the mouth of the Brahe and hauled them about a kilometre upstream. It then handed over the and rafts to the second steamer for the remaining to the locks at Bromberg. The transport service was profitable and the number of chain boats was increased to four. On 30 April 1894, the Minister of Trade and Industry and the Minister of Public Works extended the concession by another 25 years.

Neckar

By 1878, the first chain boat had also entered service on the River Neckar between

However, the regulation of the flow of the river by locks in the 1930s, which enabled it to be upgraded into a major waterway, spelt the end of the hitherto still profitable Neckar chain boats and their replacement by large barges.

Havel and Spree

On the River Havel, too, there was a short period of trials with chain boats. Although the flow of Havel has always been low, nevertheless a large number of laden barges could be towed inexpensively using a chain steamer. On the Havel and Spree rivers, between Pichelsdorf near the city of

In the Havelland there were numerous brick factories whose products were transported almost exclusively by ship. In summer 1894, chain boats on the Havel and Spree were withdrawn. The development of the steam-driven tugboat with screw propellers had superseded them.

Chain boats were also used on the River Main in the period from 1886 to 1936. The chain was laid in the navigable section of the river between

Chain boat

Das Archiv für Seewesen Band 5 Heft X 1869 S468b

The chain boat hauled itself along by means of a chain laid in the river bed. In order to do this, the chain was lifted out of the water by a boom at the bow of the vessel and ran down the deck, following the longitudinal axis of the ship, to the chain drive in the middle. Power was transferred from the steam engine to the chain primarily through a drum winch. From there, the chain was led across the deck to the boom at the

s mounted at the front and rear, it was possible to relay the chain in the middle of the river again even at river bends.

had to be paid for by the chain shipping companies themselves and was made of seamless steel links. The individual links were from good, weldable bars with a low carbon content. Depending on the section of the river the bars had a typical thickness of . Despite that, there were frequent breakages. The chain had shackles at an interval of several that could be opened when two chain boats met. Most of these high quality chains were made in England or France.

Encounter between boats travelling in opposite directions

If two chain boats met, a complex manoeuvre was necessary in which one boat passed the chain, using an auxiliary chain, to the other boat. This procedure meant a delay of at least 20 minutes for the boat travelling upstream, while the ship heading downstream suffered a delay of about 45 minutes as a result of the manoeuvre. The introduction of auxiliary engines enabled chain boats to travel downstream under their own power without using the chain, thus avoiding the need for these time-consuming operations.

Trials with "endless" chains

To avoid the large cost of buying a chain or cable, trials were carried out on the Rhône by Dupuy de Lome using an "endless" chain. The boat used its own chain, which was lowered by the forward boom into the water; its weight taking it down to lie on the river bed. At the stern, the chain was pulled up from the water again and hauled forward along the deck of the ship by the chain drive. Assuming that the lower part of the heavy, self-contained chain was unable to slide on the river bed, the ship could move forward. This type of propulsion was never used commercially because sufficient power transfer was only possible if the chain was the right length for the conditions. If the water was too deep, the length of the chain resting on the river bed became too short to generate the required friction. If the water was too shallow, the length of chain in the river became too great, and would not stretch out but lie in coils on the bottom. So variations in river depth complicated the handling of the vessel considerably.

Concessions

Chain shipping companies required a licence to operate chain boats. This concession guaranteed the company the sole right for this type of ship transport. Since the purchase of the chain and the chain boats represented a high financial burden for the operator, the concession had to offer some degree of security. But this did not eliminate competition from the railways, from paddle steamers or from normal towed barges. In return, the rights and obligations of the mariners were regulated in the concession. For example, every barge had to be transported at rates set by the state.

Comparison with paddle steamers

Chain boats not only had to face competition with the railways, but also on the waterways themselves. Compared with

s, chain steamers had advantages anywhere where the conditions were difficult for navigation, such as rapids, sharp bends in the river and shoals.

Currents and flow velocity

On a paddle wheel or screw steamer, water is pushed backwards in order to move it forward. A significant part of the energy is converted into turbulence and so is not available for the propulsion of the ship. The chain steamer, however, pulls forward on a solid chain and so can turn a much larger proportion of its steam power into thrust.Georg Schanz: "Studien über die bay. Wasserstraßen Band 1, ''Die Kettenschleppschiffahrt auf dem Main''", 1893, C.C. Buchner Verlag, Bamberg, pp. 1–7 –

by Digitalis, Bibliothek für Wirtschafts- und Sozialgeschichte, Cologne, retrieved 29 October 2009 For the same tractive force, it reduced coal consumption by about two thirds. At faster river flow rates, the advantage shifts more and more in favour of the chain steamer. In 1892, Ewald Bellingrath introduced the following general rule: at an average river gradient of 0.25 ‰ paddle steamers are superior. Between 0.25‰ and 0.3‰ both types of craft are equivalent. Above 0.3‰ the chain boat has the advantage. On gradients above 0.4‰ paddle steamers find it increasingly difficult to make headway and from 0.5‰ are completely unable to haul barges. Practical experience showed that free-running, paddle tugboats capable of could achieve a speed of about against a river current of . Thus they could provide a commercially viable service in currents of up to . Even larger gradients could be negotiated if they were only over a short distance. By slackening the tow ropes, paddle steamers could overcome the obstacle. By the time the attached barges entered the faster-flowing area, the steamer had already sailed past it and was able to generate its full traction again. At flow rates above , the power output would drop to zero. Many of the steeper sections of river were relatively short and could be overcome by paddle steamers using the manoeuvre described. However, fast currents when rivers were in spate could also be problematic for chain boats. Depending on the nature of the river bed, strong movements of

and stones. A river bed with a large number of ledges or large boulders – such as on some sections of the Danube – caused the chain to become snagged and was a major hindrance to chain boats. The water churned up by paddle steamers also resulted in significantly greater wave action, which led to a risk of increased shore damage. The additional currents and waves they generated also caused extra resistance for the towed barges. Behind a chain boat, by contrast, the water was calm.

Depth

Some chain boats had a shallow draft of just designed for use in very low water levels and thus adapted to the circumstances of many rivers of the time. Even at a depth of it was still possible to operate an effective service on the Neckar. Steamers, however, required significantly greater depths of to operate commercially. Moreover, in strong currents, the minimum water depth for steamers was greater. Tugboats with screw propulsion also need a greater water depths to be able to work effectively. Only a propeller that is deep under the water, can produce sufficient propulsion. Chain ships not only had a shallow draft; but their technical principle was also advantageous for low levels of water: in shallow waters, the chain rises at a shallow angle and a very high proportion of steam power could be converted into thrust. If the water depth was very high, it increased the proportion of energy needed to lifting the chain. The chain's weight exerted a force that was directed obliquely downwards and the efficiency decreased. In addition, maneuverability reduced with increasing depth.

Investment costs

The chain itself entailed high investment costs for the shipping company. On the section of the Main river, between

and Kitzingen it is estimated that the cost of the first chain, including laying, was over one million marks. This corresponded almost exactly to the total price for the eight chain boats that were to be used on that section. The chain had to be continually maintained and had to be renewed approximately every 5 to 10 years. In addition to the cost of the chain was the cost of the conversion of

that, on this route, came to about 300,000 marks. This conversion was necessary because the chain used by the chain boats and the cables used by the ferries were not allowed to cross. So the usual cable ferries had to be converted into reaction ferries.

Flexibility

The first chain ships could only operate when attached to the chain; that is, they used the chain when travelling both upstream and downstream. When two chain boats travelling in opposite directions met, they had to carry out special passing manoeuvres, which resulted in a major loss of time. On the Neckar river with seven chain boats that meant six passing manoeuvres costing at least five hours for those travelling downstream. In order to avoid this time-consuming operation, barges on certain stretches of river in France passed the chain of barges from one chain steamer to another. Such a transfer, however, also took up a significant amount of time. Barges were normally only towed upstream. When travelling downstream the barges were usually just allowed to drift with the current in order to save money, In strong currents, operating a long string of barges was quite dangerous. Should a chain boat be forced to stop suddenly (for example, if the chain broke), there was a serious risk that following ships would run into it and thus cause an accident. In the early days of the chain boat, paddle steamers were slower at making their way upstream that chain boats. When heading downstream, however, they were faster and could also haul barges with them. In addition to the technical limitations of chain boats, their owners were constrained by licence rules, which, for example, laid down the order of the movement and transport fees. They were not therefore as flexible in responding to supply and demand as the paddle steamer companies.

The demise of chain boats

One reason for the demise of chain boats was the improvement in the technical performance of the new paddle steamers. They were able to deliver greater traction for lower coal consumption. The

on the paddle steamer, based on its power output, needed only about half the amount of coal. Chain steamers were not able to take advantage of these compound steam engines because of their uneven operation."Der Schiffszug auf den Wasserstraßen."

/ref> At the same time, chain shipping companies suffered from high investment and maintenance costs. Another reason for their demise was the canalization of rivers. On the Elbe a lot of current regulating work had been carried out, which evened out the gradient, reduced bends in the river and removed the shallows. As a result, the advantages of chain ship were reduced. On the Main and Neckar, numerous dams and locks were also added, which created artificial barriers for the chain boats. The damming of the river increased water depths and reduced flow rates. In particular, long strings of barges had to be divided at the locks and fed through individually, causing a considerable loss of time.
