The class comprised ''{{HNLMS|Bali|1857|2}}'', ''{{ship|Japanese warship|Kanrin Maru||2}}'', ''{{HNLMS|Soembing|1856|2}}'', ''{{ship|Japanese warship|Chōyō Maru||2}}'' and ''{{ship|Japanese warship|Denryū Maru||2}}''.
== Dutch and Japanese Naval Plans in the 1850s == === Dutch program for screw propulsion === Under the 1852 naval program, the Dutch shifted to using screw propulsion in their navy. The smallest type of ship of the 1852 program was ''Vuurpijl''. She would have 70 nominal hp, and was later known as ''Montrado''. Shortly after her launch the 70 nominal hp configuration of ''Montrado'' proved too small for her intended role. This is how the plan for a somewhat larger type of ship came up.
In May 1855 the new minister for the navy De Smit van den Broecke presented the overall 'Plan 1855' for the fleet at home and in the East Indies. The heaviest ships of the new fleet would be 3 screw steam frigates of 400 hp, 50 guns and 500 men, to be stationed in the Netherlands. The standard fighting warship for the East Indies would be a screw corvette of 250 hp, 12 30-pounders and 125 men, of which 12 would be built. For policing the many outposts in the Indies 15 'screw steamships' of 100 hp, 12 guns and 85 men would be built. These would be supplemented by small paddle ships that would navigate rivers and shallow waters.<ref>{{Cite news |url= https://resolver.kb.nl/resolve?urn=ddd:010250703:mpeg21:p001 | work = De Tijd| title=Amsterdam, 11 Mei| date=12 May 1855}}</ref>
The ships of the Bali class fit the 100 hp 'screw steamships' of the 1855 plan.
=== The Japanese fleet program === From 1639 onward, the Dutch had been the only western power allowed to trade in Japan. By the early nineteenth century other western powers also attempted to gain access to Japan. On 8 July 1853 the American Commodore Perry visited Japan for the first time, and threatened to use force if Japan would not open up to trade. Shortly after, Japan asked the Netherlands for ships to counter the threat. On August 22, 1854, the Dutch paddle-steamer ''Soembing'' arrived in Nagasaki. She was almost brand new, and made a good impression on the Japanese. The Dutch and Japanese then started a plan and treaty that involved the creation of a modern Japanese navy and a strengthening of the Dutch (trade) position in Japan and on Dejima.
Creating a modern mid-nineteenth century navy from scratch was a huge project. It required hundreds of people to be educated in naval sciences, the underlying natural sciences, and the science and crafts of sailing and maintaining ships. To start this, the Dutch sent a detachment of officers and men to instruct the Japanese. In order to have training material Japan would buy a handful of Dutch merchant and warships. The Japanese government primarily thought about screw warships.
In a February 1855 report, the minister of the colonies cited Captain-lt Fabius about the type of ship that he thought to be required by Japan. Fabius thought of a flush-deck corvette of 10-12 guns and 100 hp. The minister for the navy stated that such a ship could not be bought, and therefore had to be built. There was no space at the state shipyards, and therefore the work had to be relegated to a private shipyard. This would take time, and therefore a plan was made. In 1855 Fabius would again go to Japan to teach. In 1856 a very large scale model of the screw corvette would be delivered. In 1857 the screw corvette would be delivered. Of course the corvette had to be constructed in such a way that it could also be used in the Dutch navy, if the deal would somehow be cancelled.{{sfn|van der Chijs|1867|p=135}}
Shortly after the order for the screw corvette was communicated, the Japanese government expressed its desire to buy a second corvette. Delivery for this second ship was planned for 1858. Meanwhile, local Dutch officials proposed to gift a steamship to the Japanese while these corvettes were on order.{{sfn|van der Chijs|1867|p=144}} During a second visit to Japan ''Soembing'' was therefore handed over to the Japanese government on 25 August 1855 and renamed Kankō Maru. ''Kankō Maru'' was suitable as an instruction ship. As a side-wheeler she also required less maintenance than a screw ship, and did not require a dry dock.
== Ordering and Construction == === Orders for the first two ships === The first attempts to build small screw propelled ships, ''Medusa'' and ''Vuurpijl'' / ''Montrado'', were initially not successful.<ref name=RC03111855 /> The combination with the already high workload at the state shipyards then probably gave the naval minister the courage to attempt construction by a private shipyard. On 3 July 1855 the minister for the navy De Smit van den Broecke defended the final navy budget for 1855, including Plan 1855, in the first chamber of the House of Representatives. He explained that two ships of a completely new type (that of 100 hp) had been ordered at Fijenoord. The step to contract with Fijenoord had been taken because it was especially important to get machinery right. The shipyard was free to subcontract others.<ref>{{Cite news |url= https://resolver.kb.nl/resolve?urn=ddd:010245918:mpeg21:p003 | work = De grondwet | title= Staten Generaal | date=4 July 1855 }}</ref> Later in 1855 it became known that construction of the hull of one of these ships had been subcontracted to another shipyard,<ref name=RC03111855>{{Cite news |url= https://resolver.kb.nl/resolve?urn=ddd:010396662:mpeg21:p002 | work = Rotterdamsche courant | title= Staten-Generaal | date= 3 November 1855 }}</ref> Fop Smit in Kinderdijk, his shipyard later became known as L. Smit en Zoon.
=== Construction === Shipyard Fijenoord contracting with Fop Smit in Kinderdijk was not unusual. Fop Smit had gained a good reputation in building modern ships. Fijenoord was specialized in engines and iron ships, making it more costly to construct the wooden hulls for the Bali's at her own yard at Fijenoord. To the public it meanwhile seemed as if both ships were getting constructed for the Dutch navy. In early 1856 the lead ship ''Bali'' was expected to be finished in April, and commissioned May 1.<ref>{{Cite news |url= https://resolver.kb.nl/resolve?urn=ddd:010113001:mpeg21:p002 | work = Rotterdamsche courant | title= Binnenland | date= 27 March 1856 }}</ref> This would have amounted to an unusually short time between launch and commissioning, and indeed this news proved false. However the name of the lead ship was now public.
The next news about the ''Bali'' class was that in early April 1856 a 1/40 scale model of ''Bali'' was almost finished. Two model makers had worked on it for 1.5 years, and now it would be sent to The Hague, and then to Japan as a gift to the emperor.<ref name=UP04041856>{{Cite news |url= https://resolver.kb.nl/resolve?urn=ddd:010777002:mpeg21:p002 | work = Utrechtsche provinciale en stads-courant | title= Utrecht 4 April | date= 4 April 1856 }}</ref> ''Bali'', with machines made by Fijenoord, was then launched on 8 October 1856.<ref>{{Cite news |url= https://resolver.kb.nl/resolve?urn=ddd:010086745:mpeg21:p002 | work = Algemeen Handelsblad | title= Kinderdijk, 8 Oct. | date= 10 October 1856 }}</ref>
Shortly after the news about the model of ''Bali'', in May 1856, it had become known that Huyssen van Kattendijke would sail a screw schooner to Japan. It was under construction for Japan on a Dutch private shipyard and would leave in September 1856.<ref>{{Cite news |url= https://resolver.kb.nl/resolve?urn=ddd:010113059:mpeg21:p002 | work = N.R.C. | title= Binnenland | date= 25 May 1856 }}</ref> On 12 November 1856, Fop Smit then launched a 'screw schooner of war' with machines by Fijenoord.<ref name=AH15111856>{{Cite news |url= https://resolver.kb.nl/resolve?urn=ddd:010086781:mpeg21:p002 | work = Algemeen Handelsblad | title= Rotterdam, 13 Nov. | date= 15 November 1856 }}</ref> Giving a ship a name was an essential part of launching a ship, and so it was kind of obvious that strange things were happening. In January 1857 it finally became known that Huyssen van Kattendijke would sail the steamship ''Japan'', which had been built for the Japanese government in the Netherlands, to Japan.<ref>{{Cite news |url= https://resolver.kb.nl/resolve?urn=ddd:010776172:mpeg21:p001 | work = Utrechtsch provinciaal en stedelijk dagblad | title= Utrecht 20 Januarij | date= 20 January 1857 }}</ref> ''Japan'' would be renamed ''Kanrin Maru'' on arrival in Japan.
''Soembing'' was the third ship of the class. The name was a direct consequence of the criticism that the government received for giving away the paddle-steamer ''Soembing'' to Japan in August 1855. The construction of a new ''Soembing'' would make clear that the strength of the navy would not suffer from giving away the old ship. ''Soembing'' was laid down at the (state shipyard) Rijkswerf Vlissingen on 17 May 1856.<ref>{{Cite news |url= https://resolver.kb.nl/resolve?urn=ddd:000011643:mpeg21:p002 | work = Dagblad van Zuidholland en 's Gravenhage | title= 's-Gravenhage, 20 November. | date= 21 November 1856}}</ref> On 29 November 1856 she was launched as the third ship of the class.<ref>{{Cite news |url= https://resolver.kb.nl/resolve?urn=ddd:010901527:mpeg21:p001 | work = Middelburgsche courant | title= Marine en Leger | date= 2 December 1856}}</ref>
Chōyō Maru, built by Cornelis Gips in Dordrecht as ''Jedo'', was the fourth ship of the ''Bali'' class. That is, ''Chōyō Maru'' was ordered within a few months of ''Kanrin Maru''. She also had 100 hp engines.<ref name=NR22081857>{{Cite news |url= https://resolver.kb.nl/resolve?urn=ddd:010112215:mpeg21:p001 | work = N.R.C. | title= Binnenland | date= 22 August 1857}}</ref> During ordering she was referred to as one of 'two screw corvettes' ordered by Japan.{{sfn|van der Chijs|1867|p=145}} It's therefore very unlikely that she was built to a different design than ''Kanrin Maru''. There is also a direct claim that she was built to the same specifications as ''Kanrin Maru''.{{sfn| Hillsborough | 2014 |p= chapter 5}} To be absolutely certain one would need measurements of ''Chōyō Maru''.
Denryū Maru, built by Cornelis Gips in Dordrecht as ''Nagasaki'', was the fifth ship of the ''Bali'' class. That is, she was built by the same order, at the same time and by the same shipyard. There is also a clear statement that it was built to the same model as Chōyō Maru.<ref name=AH03091857>{{Cite news |url= https://resolver.kb.nl/resolve?urn=ddd:010091280:mpeg21:p002 | work = Algemeen Handelsblad | title= Dordrecht, 3 Sept. | date= 5 September 1857}}</ref> Denryū Maru also had engines by Fijenoord.<ref name="Rotterdam, 25 Jan">{{Cite news |url= https://resolver.kb.nl/resolve?urn=ddd:010130333:mpeg21:p002 | work = Nieuw Amsterdamsch handels- en effectenblad | title= Rotterdam, 25 Jan. | date= 27 January 1858}}</ref>
==Characteristics of the Bali class== The Dutch navy was rather inconsistent in classifying its ships. This was especially true for the smaller charters, and was further complicated by politics, changes in technology, and changes to armament and sail plans. The ''Bali'' class was especially affected by this. As a name for the type the Dutch first talked about a 'screw corvette',{{sfn|van der Chijs|1867|p=136}} then a war steamer,<ref name=UP04041856 /> and then a screw schooner.<ref name=AH15111856 /> Before being commissioned ''Bali'' was in one group with ''Montrado'' as Schooners with steam power.{{sfn|Swart |1856|p=157}}
When the Dutch navy introduced the classes, ''Bali'' and ''Soembing'' were classified as screw steamships fourth class in 1857.{{sfn|Swart |1857|p=424}} This continued in 1858,{{sfn|Swart |1858|p= 249}} 1859,{{sfn|Swart |1859|p= 97}} and 1860.{{sfn|Swart |1860|p= 370}} In 1861 ''Soembing'' then became a screw ship 3rd class, while ''Bali'' remained a screw ship 4th class.{{sfn|Swart |1861|p= 184}} In 1866 this was reverted, and ''Bali'' (and ''Montrado'') also became screw steam ships 3rd class.{{sfn|Swart |1866|p= 2nd part, 22}} The event of 1861 suggests that ''Bali'' and ''Soembing'' were ships of a different type. This is not the case, even though the different classification might have had a reasonable temporary cause, probably in the armament the ships carried.
In the more or less final classification of Dutch screw steamships, the steam corvettes became 2nd class, the gunvessels were rated 4th class, and the Bali class was rated in the 3rd class. The ships of the third class were called 'sloops' in English. An English sloop class of a size comparable to the Bali class was e.g. the Swallow-class sloop.
===Design=== The dimensions of ''Bali'' and ''Soembing'' are given by Tideman. Bali was given as long 40.80 m on the water line, and Soembing 41.10. Beam on the waterline outside the hull was 8.74 and 8.52 m, depth 3.28 and 3.38 m. Displacement was 604 and 608 ton. The big difference with the preceding ''Montrado'' of 40.0 m and 400 ton, was that ''Montrado'' had a draught of only 2.68 m. Furthermore, the ''Bali'' class were about twice as small as the next bigger ships, the ''Medusa'' class of Corvettes with auxiliary power.{{sfn|Tideman |1859|p= 198}}
The unknown exact measurements of ''Japan'' and slight differences in measurements between ''Bali'' and ''Soembing'' create some doubt about whether the Bali class was really of one design. However, from the trials of ''Bali'', there is a statement that: 'The ''Bali'' is in all parts shaped the same shape as the screw steamship recently built for Japan'.<ref name=NS30051857>{{Cite news |url= https://resolver.kb.nl/resolve?urn=ddd:010789599:mpeg21:p002 | work = Nederlandsche Staatscourant | title= Binnenlandsche Berigten | date= 30 May 1857}}</ref> This is also a logical explanation for sending a model of ''Bali'' to Japan, instead of a model of ''Japan'' herself.
The differences between ''Bali'' and ''Soembing'' have two explanations. For ''Bali'' a design drawing gives some measurements. Length between perpendiculars: 41.00 m, beam on the outside of the inhouten (frames?) 8.50 m, draught: 3.40-3.85 m, depth of hold 5.00 m. For ''Soembing'' there is also a blueprint, it has: Length between perpendiculars 41.00 m, beam inside the hull 8.40 m, depth of hold inside 4.80 m, draught 3.50-3.90 m. It shows that both ships were designed with the same length, and Tideman later noted different lengths caused by how deeply the ships were immersed. A real difference in the hull of ''Soembing'' was that it had a fuller bow, so guns could be placed to fire straight ahead.{{sfn|de Waal |1879|p= 229 }}
===Armament=== In 1859 the armament plan for the ''Bali'' class foresaw 4 long 12-pdr cannon and 4 30-pdr carronades, weighing 9,850 kg{{sfn|Rees|Brutel de la Riviere |1859|p=343}} ((4*1,500)+(4*960)=9,840) This was probably put in place, because till 1861 ''Bali'' was noted to carry 8 guns. ''Soembing'' was planned to start out with the same armament of 4 long 12-pdr and 4 30-pdr carronades.{{sfn|Obreen|1858|p= 84}}
In 1869, ''Bali'' had 10 guns: 2 long 12-pdr cannon and 8 30-pdr carronades,{{sfn|Departement van Marine |1869|p=111 }} weighing ((2*1,500)+(8*960))=10,680 kg. By then the armament of ''Soembing'' differed significantly from that of ''Bali''. ''Soembing'' then had 2 16 cm RML and 4 medium 30-pdr No 1 or 2. The 16 cm RML weighed 1,792 kg, the medium 30-pdr weighed 1,650 kg, so total weight was ((2*1,792)+(4*1,650)=) 10,184 kg.
A different armament for ''Soembing'' could have caused her re-classification as a 3rd class screw steam ship. The re-armament which was visible in 1869 gave her the same armament that some Vesuvius-class sloops later had.{{sfn|Tweede Kamer|1875|p=Bijlage A Algemeen Overzigt der Schepen en vaartuigen van oorlog op den 1sten Augustus 1875}} If one considers that the ''Vesuvius'' class was designed because the ''Bali'' class could not mount a heavy battery,{{sfn|de Waal |1879|p= 229 }} it seems logical that ''Soembing'' got in the same class as the ''Vesuvius'' when she was able to mount the same armament. However, the re-classification of ''Soembing'' took place on 1 January 1861. It seems that at that time the armament of ''Bali'', ''Soembing'' and ''Vesuvius'' was the same.
===Propulsion=== The ''Bali'' class had machines of 100 nominal horsepower made by Fijenoord. The diameter of the cylinder was 81.2 cm, stroke 68.5 cm. The boilers were designed to allow 75 turns. The first propeller that ''Bali'' used, was only 2.74 m diameter, and would allow verification of this design. During the first trial, on the Meuse, the engine indeed made 74-75 turns while pressure was 15 kg / square inch. The slip of the small propeller was 33%, much too high. As a consequence Bali made only {{convert|7.8|kn|km/h|abbr=out|lk=in}}. Now the second (normally the reserve) propeller was made for ''Bali''.<ref>{{Cite news |url= https://resolver.kb.nl/resolve?urn=ddd:010776228:mpeg21:p001 | work = Utrechtsch provinciaal | title= Utrecht 26 Maart. | date= 26 March 1857}}</ref> This bigger propeller got a 3 m diameter and speed of 4.87 m.{{sfn|Huygens |1857 |p= 2nd part 179 }}
In May 1857 ''Bali'' made her second trials in Hellevoetsluis, using the bigger propeller. With an average load she made {{convert|8.25|kn|km/h|abbr=out|lk=in}}. The boilers had a pressure of 12 kg and a vacuum of 25.5–26 cm, while the propeller made 60-62 turns. The slip of the propeller was now only 16%, which was low for such a small ship. The machines worked very smoothly, and the ship responded very well to the rudder.<ref name=NS30051857 /> In all probability the firemen could heat the boilers till 15 kg pressure, turning up the machine to make 65 turns. ''Bali'' would then attain the designed speed of {{convert|8.5|kn|km/h|abbr=out|lk=in}}.{{sfn|Huygens |1857 |p= 2nd part 182}}
The ''Bali'' class were nevertheless meant to sail most of the time. The first reports about the sailing qualities of ''Kanrin Maru'' were very positive.<ref name=NS30051857 />
