Pontianak-class Gunvessel
The ''Pontianak'' class was a class of steam screw gunvessels of the Royal Netherlands Navy. The Dutch colonial navy in the 1870s In the 1870s the navy in the Dutch East Indies consisted of an auxiliary squadron of four ships from the Netherlands, and the colonial navy of 22 ships. The auxiliary squadron was primarily responsible for external defense. The ships of the colonial navy (''Indische Militaire Marine'') were meant for transport and flotilla services. In the early 1870s the demands that a war against Aceh would place upon the colonial navy were severely underestimated. When the Aceh War The Aceh War ( id, Perang Aceh), also known as the Dutch War or the Infidel War (1873–1913), was an armed military conflict between the Sultanate of Aceh and the Kingdom of the Netherlands which was triggered by discussions between represe ... actually erupted in 1873, its ships proved to be too defective and too few in number.

Van Vlissingen En Dudok Van Heel
Van Vlissingen en Dudok van Heel was a famous nineteenth-century Dutch machine factory. It built steam engines and machinery for the sugar industry and for maritime purposes, as well ships, rolling stock and large metal structures like the Moerdijk bridge and a floating dock. In 1871 it was reorganized to become the public company Koninklijke Fabriek van Stoom- en andere Werktuigen. In a second reorganization in 1890, parts of it were saved and continued under the name Koninklijke Nederlandsche Fabriek van Werktuigen en Spoorwegmaterieel, renamed to Werkspoor in 1927. Van Vlissingen en Dudok van Heel Early years The company was founded as the 'Van Vlissingen' company in 1826. The founder was Paul van Vlissingen (1797–1876), who was also one of the founders of the Amsterdamsche Stoomboot Maatschappij (ASM). In 1828 Abraham Dudok van Heel (1802–1873) became a partner, and the name was changed to Fabriek van Stoom- en Andere Werktuigen, onder de firma Van Vlissingen & Dud ...

Galle
Galle ( si, ගාල්ල, translit=Gālla; ta, காலி, translit=Kāli) (formerly Point de Galle) is a major city in Sri Lanka, situated on the southwestern tip, from Colombo. Galle is the provincial capital and largest city of Southern Province, Sri Lanka and is the capital of Galle District. Galle was known as ''Gimhathiththa'' before the arrival of the Portuguese in the 16th century, when it was the main port on the island. Ibn Batuta, a Moroccan Berber Muslim traveller in the 14th century, referred to it as ''Qali''. Galle reached the height of its development in the 18th century, during the Dutch colonial period. Galle is the best example of a fortified city built by the Portuguese in South and Southeast Asia, showing the interaction between Portuguese architectural styles and native traditions. The city was extensively fortified by the Dutch during the 17th century from 1649 onwards. The Galle fort is a world heritage site and is the largest remaining fort ...

Weather Helm
Weather helm is the tendency of sailing vessels to turn towards the source of wind, creating an unbalanced helm that requires pulling the tiller to windward (i.e. 'to weather') in order to counteract the effect. Weather helm is the opposite of lee helm. It is generally less troublesome than lee helm. Overview Weather helm is the result of a leeward and aft shift of a vessel's vector center of effort (the direction to which the force generated by the sails is pushing). This shift is caused by excess pressure on the mainsail, which overpowers the windward lateral resistance generated by the jib (or other head sail) and keel or centerboard. This results in an imbalance of force at the stern from windward, and the craft pivots about the center of drag (often near the center of the keel or centerboard), causing the bow to drive windward. Weather helm does not only result from an overpowered main; when a vessel is heeling to leeward, the aft component of keel drag is moved to windwar ...

Ship Motions
Ship motions are defined by the six degrees of freedom that a ship, boat or any other craft can experience. Reference axes The '' vertical/Z axis'', or ''yaw axis'', is an imaginary line running vertically through the ship and through its centre of mass . A yaw motion is a side-to side movement of the bow and stern of the ship. The '' transverse/Y axis'', ''lateral axis'', or ''pitch axis'' is an imaginary line running horizontally across the ship and through the centre of mass. A pitch motion is an up-or-down movement of the bow and stern of the ship. The '' longitudinal/X axis'', or ''roll axis'', is an imaginary line running horizontally through the length of the ship, through its centre of mass, and parallel to the ''waterline''. A roll motion is a side-to-side or port-starboard tilting motion of the superstructure around this axis. Rotational There are three special axes in any ship, called longitudinal, transverse and vertical axes. The movements around them a ...

Bilge Keel
A bilge keel is a nautical device used to reduce a ship's tendency to roll. Bilge keels are employed in pairs (one for each side of the ship). A ship may have more than one bilge keel per side, but this is rare. Bilge keels increase hydrodynamic resistance to rolling, making the ship roll less. Bilge keels are passive stability systems. On commercial shipping the bilge keel is in the form of a strake, or small keel or blister, running along much of the length of the hull. They are typically fitted one on each side, low down on the side of the hull, so as not to increase the draft of the vessel. In battleships they were often quite large and used as part of the torpedo protection system. A bilge keel is often in a "V" shape, welded along the length of the ship at the turn of the bilge. Although not as effective as stabilizing fins, bilge keels have a major advantage in their low impact on internal ship arrangements. Unlike fins, bilge keels do not have any components inside t ...

Vesuvius-class Sloop
The ''Vesuvius'' class was a class of steam screw sloops of the Royal Netherlands Navy. The class comprised ''Vesuvius'', ''Cornelis Dirks'', ''Reinier Claessen'', ''Het Loo'', ''Reteh'' and ''Prinses Maria''. Dutch Naval Plans in the 1850s Plan 1855 The Dutch naval plan 1855 stated that the steam corvette of 250 hp and 12 30-pounders (the Groningen-class corvettes) would be the standard warship for the Dutch East Indies. However, the plan also recognized that in the East Indies, there were 'too many points to occupy, too many seas to patrol, and too many corners to penetrate' to use only these still costly ships. The plan 1855 therefore specified a second type of ships for the indies: the sloop of 100 hp. Regular service in the East Indies required 12 such sloops. The West Indies three more, and 2 were required for replacement. In total 17 sloops would be required in peace time, and 20 in times of war.

Composite Ship
The technique of composite ship construction (wooden planking over a wrought iron frame) emerged in the mid-19th century as the final stage in the evolution of fast commercial sailing ships. Construction of wrought iron hulled vessels had begun in the 1820s and was a mature technology by the time of the launch of the SS ''Great Britain'' in 1843. However, iron hulls could not be sheathed with copper alloy (due to bimetallic corrosion) and so would become festooned with drag-inducing weed during long voyages in the tropics. The wooden planking of a composite ship allowed the copper sheathing essential for fast ocean crossings under sail while the iron frame made the ship relatively immune from hogging and sagging, and took up less interior space than wooden framing. The brief reign of composite clippers as the fastest mode of transport between Europe and Asia was brought to a close by the opening of the Suez Canal in 1869 and ongoing improvement in the performance of s ...

Fijenoord
Fijenoord () was a shipbuilding company and machine factory in Rotterdam the Netherlands from 1823 to 1929. In 1929 it merged with Wilton to become Wilton-Fijenoord. Early years First ships and activities of the NSM In 1822 a number of businessmen and women and the engineer Gerhard Mauritz Roentgen. founded Van Vollenhoven, Dutilh en Co. In June 1823 ''De Nederlander'', the first Dutch steamboat (with English engines) started its service, which would become a line between Rotterdam and Antwerp. In 1824 the Nederlandsche Stoomboot Maatschappij (NSM, but also NSBM) was founded and succeeded to Van Vollenhoven, Dutilh en Co. Roentgen became one of its two executives. NSM was primarily a shipping line. Its first business activities consisted of founding a number of lines from Rotterdam to Antwerp, Veere, Nijmegen and Arnhem. The required ships and in particular their engines, were designed by Roentgen. The first hulls were built by other companies, but the steam engines were a ...

Aceh War
The Aceh War ( id, Perang Aceh), also known as the Dutch War or the Infidel War (1873–1913), was an armed military conflict between the Sultanate of Aceh and the Kingdom of the Netherlands which was triggered by discussions between representatives of Aceh and the United States in Singapore during early 1873.Ricklefs (2001), p. 185–88 The war was part of a series of conflicts in the late 19th century that consolidated Dutch rule over modern-day Indonesia. The campaign drew controversy in the Netherlands as photographs and accounts of the death toll were reported. Isolated bloody insurgencies continued as late as 1914 and less violent forms of Acehnese resistance continued to persist until World War II and the Japanese occupation. Background For much of the 19th century, Aceh's independence had been guaranteed by the Anglo-Dutch Treaty of 1824 and its status as a protectorate of the Ottoman Empire since the 16th century. During the 1820s, Aceh became a regional political ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dutch East Indies
The Dutch East Indies, also known as the Netherlands East Indies ( nl, Nederlands(ch)-Indië; ), was a Dutch colony consisting of what is now Indonesia. It was formed from the nationalised trading posts of the Dutch East India Company, which came under the administration of the Dutch government in 1800. During the 19th century, the Dutch possessions and hegemony expanded, reaching the greatest territorial extent in the early 20th century. The Dutch East Indies was one of the most valuable colonies under European rule, and contributed to Dutch global prominence in spice and cash crop trade in the 19th to early 20th centuries. The colonial social order was based on rigid racial and social structures with a Dutch elite living separate from but linked to their native subjects. The term ''Indonesia'' came into use for the geographical location after 1880. In the early 20th century, local intellectuals began developing the concept of Indonesia as a nation state, and set the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
