Evertsen-class Frigate
The ''Evertsen'' class was a class of steam frigates of the Royal Netherlands Navy. The class comprised ''Evertsen'' and ''Zeeland'' Dutch Naval Plans in the 1850s Plan 1852: First reaction to the screw The first coherent Dutch reaction to the appearance of screw driven warships was the plan 1852. It was a plan conceived by a commission of naval officers and augmented by the secretary for the navy. It led to orders to construct four ships in November 1852. These were: the screw frigate ''Wassenaar'', the two screw corvettes of the Medusa class, and one screw schooner (''Montrado''). This was a plan to ''start'' the construction of screw driven warships. When a second expensive screw frigate (the ''Evertsen'') was laid down in late 1854, the Dutch house of representatives was deeply worried by the apparent demise of the Dutch navy and the absence of a plan to make her effective again. Plan 1855 On 8 February 1855 Smit van den Broecke became the new Dutch Secretary for the na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vlissingen Naval Base
Vlissingen Naval Base (Marine Etablissement Vlissingen) was a base for the Admiralty of Zeeland, and later the Dutch Navy. It has a number of major marine facilities of historic significance. It housed a shipyard for the Admiralty of Zeeland, and the national shipyard Rijkswerf Zeeland. Shipyard de Schelde would take over the grounds of the Rijkwerf, and still continues to build warships as Damen Schelde Naval Shipbuilding. Location of Vlissingen The location of Vlissingen on the mouth of the Schelde means that it can easily be reached by the biggest ships. Such was the case in the Middle Ages and this is still the case in the 21st century. What made Vlissingen a safe place for ships were the man-made facilities of the port. Large numbers of warships could lay in ordinary in the wet dock, and then be repaired either in the dry dock or on one of the slipways of the Rijkswerf. Facilities of the naval base at Vlissingen The Oosterhaven, the first dock The city walls of Vlissingen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Frigate
Steam frigates (including screw frigates) and the smaller steam corvettes, steam sloops, steam gunboats and steam schooners, were steam-powered warships that were not meant to stand in the line of battle. There were some exceptions like for example the French Napoléon class steam ship of the line was meant to stand in the line of battle, making it the world's first steam battleship. The first such ships were paddle steamers. Later on the invention of screw propulsion enabled construction of steam-powered versions of the traditional ships of the line, frigates, corvettes, sloops and gunboats. Evolution First steam warships The first small vessel that can be considered a steam warship was the ''Demologos'', which was launched in 1815 for the United States Navy. From the early 1820s, the British Navy began building a number of small steam warships including the armed tugs and , and by the 1830s the navies of America, Russia and France were experimenting with steam-powered wa ...

Ship Class
A ship class is a group of ships of a similar design. This is distinct from a ship type, which might reflect a similarity of tonnage or intended use. For example, is a nuclear aircraft carrier (ship type) of the (ship class). In the course of building a class of ships, design changes might be implemented. In such a case, the ships of different design might not be considered of the same class; each variation would either be its own class, or a subclass of the original class (see for an example). If ships are built of a class whose production had been discontinued, a similar distinction might be made. Ships in a class often have names linked by a common factor: e.g. s' names all begin with T (, , ); and s are named after American battles (, , , ). Ships of the same class may be referred to as sister ships. Naval ship class naming conventions Overview The name of a naval ship class is most commonly the name of the lead ship, the first ship commissioned or built of its design. ...

Royal Netherlands Navy
The Royal Netherlands Navy ( nl, Koninklijke Marine, links=no) is the naval force of the Kingdom of the Netherlands. During the 17th century, the navy of the Dutch Republic (1581–1795) was one of the most powerful naval forces in the world and played an active role in the Anglo-Dutch Wars, the Franco-Dutch War, and wars against Spain and several other European powers. The Batavian Navy of the later Batavian Republic (1795–1806) and Kingdom of Holland (1806–1810) played an active role in the Napoleonic Wars, though mostly dominated by French interests. After the establishment of the modern Kingdom of the Netherlands, it served an important role in protecting Dutch colonial rule, especially in Southeast Asia, and would play a minor role in World War II, especially against the Imperial Japanese Navy. Since World War II, the Royal Netherlands Navy has taken part in expeditionary peacekeeping operations. Bases The main naval base is in Den Helder, North Holland. Secondary na ...

HNLMS Wassenaar (1856)
HNLMS ''Wassenaar'', was a unique ship built for the Royal Netherlands Navy. Context The ''Admiraal van Wassenaar'' was part of the 1852 program which started the introduction of screw propelled warships to the Dutch navy. The first phase of the plan consisted of the ''Wassenaar'', two steam corvettes of the ''Medusa'' class, and the steam schooner Montrado. The ''Wassenaar'' was laid down in Amsterdam on 12 February 1853. When she was commissioned in July 1857, she was the first steam frigate of the Dutch Navy. Characteristics Design The ''Wassenaar'' was originally designed and partly built as a sailing frigate. This meant that her dimensions were the same as those of a sailing frigate laid down decades earlier, except that she was about 6.5 m longer. That she was only 6.5 m longer was due to the fact that she was meant to be a frigate with auxiliary power. Therefore, her engine was relatively small, and could be fitted with relatively small adjustments. The first captain of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medusa-class Corvette
The ''Medusa'' class was a class of two steam corvettes with auxiliary power of the Royal Netherlands Navy. The class comprised ''Medusa'', the first Dutch warship with screw propulsion, and ''Prinses Amelia''. Dutch naval plans in the 1850s Dutch reaction to the Screw Steamship In the late 1840s the English and French navies commissioned several screw frigates. The first of these were steam frigates with auxiliary power, meaning that they had only a small engine. The small engine kept other aspects of the sailing frigate; the sails, armament and its robustness, almost intact. Steam paddle frigates were still a bit faster under steam, but this was only true if there was no wind, or a head wind. With a moderate wind on a different course, the steam vessel with auxiliary power was faster. With less steam power, but a full sail plan it outran the paddle steam vessel. Therefore the comparatively cheap steam frigate with auxiliary power was superior to the paddle steam vessel in ever ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abraham Johannes De Smit Van Den Broecke
Abraham Johannes de Smit van den Broecke ( Aardenburg, 13 May 1801 - Oost-Souburg, (1 January 1875) was a career officer of the Royal Dutch Navy and a conservative minister for the navy. Early life Abraham Johannes de Smit van den Broecke was born on 13 May 1801. His parents were Abraham van den Broecke (1768-1840), mayor of Aardenburg and Adriana Jacoba de Jonge (1777-1835). Abraham's eldest brother Servaas (1798-1863) would become a notary like his father. The second brother Jacobus Cornelis (1799-1870) would become famous as a medical doctor. The third older brother Hendrik (1800-1866) became a merchant. A younger brother Philippus made career as a lawyer. At age 13 Abraham went to the Kweekschool voor de Zeevaart in Amsterdam in 1814. This was a boarding school for naval education. It's remarkable that Abraham was sent to the navy so young instead of going to university like his brothers. Early on he would succeed in making everybody refer to him by the double name ''De Smi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medemblik
Medemblik () is a municipality and a town in the Netherlands, in the province of North Holland and the region of West-Frisia. It lies immediately south of the polder and former municipality of Wieringermeer. History Medemblik was a prosperous trading town, when in 1282, Floris V, Count of Holland, successfully invaded West Friesland. He built several fortresses to control the region, one of which was Kasteel Radboud in Medemblik, and awarded Medemblik city rights in 1289. After Floris V was murdered in 1296, the local Frisian besieged the castle, but in 1297 an army from Holland thwarted their efforts to starve out the inhabitants, which included Medemblik citizens.Ben DijkhuiThe Castle at Medemblik/ref> Several more attacks took place in the following centuries. The most notorious of these happened in June 1517, when Medemblik was attacked from mainland Frisia by about 4000 pirates known as the Arumer Zwarte Hoop, led by Pier Gerlofs Donia and Wijard Jelckama.

Highflyer-class Corvette
The ''Highflyer''-class corvettes were a pair of 21-gun wooden screw corvettes built in the 1850s for the Royal Navy. Design ''Highflyer'' was ordered as a small wooden frigate to a design by the Surveyor's Department of the Admiralty on 25 April 1847; she and her sister ''Esk'' were re-designated as corvettes in 1854. These ships were envisaged as steam auxiliaries, intended to cruise under sail with the steam engine available for assistance. Commensurately they were provided with a full square sailing rig. ''Esk'' was built in exchange for HMS ''Greenock'' (which went to the Australian Royal Mail Co.) The words of the Admiralty Order stated she should be "a wood screw vessel complete of ''Highflyer''s lassin exchange when built". Propulsion ''Highflyer'' was given a geared two-cylinder horizontal single-expansion steam engine, provided by Maudslay, Sons & Field, which developed and drove a single screw. ''Esk'' was provided with an oscillating two-cylinder inclined sing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMS Euryalus (1853)
HMS ''Euryalus'' was a fourth-rate wooden-hulled screw frigate of the Royal Navy, with a steam engine that could make over . She was launched at Chatham in 1853, was 212 feet long, displaced 3,125 tons and had a complement of 515 (this varied slightly as the Naval Standards varied). At the time of the Bombardment of Kagoshima she carried 35 guns, not counting approximately 16 carronades. Seventeen of her guns were breech-loading Armstrong guns. She carried 230 tons of coal, and provisions for about three months, together with over 70 tons of shot and shell. Service history In December 1853, G. Ramsay was appointed captain. The ship served in the Baltic Campaign in 1854–1855. On 2 April 1855 she gave HMS ''Imperieuse'' a tow, after the ship had run aground; the previous day, off the Reefness Lighthouse (Røsnæs lighthouse) in Kalundborg, Denmark. As part of the Anglo-French fleet, she took part in the bombardment of Sveaborg (now Suomenlinna, Finland) on 7–9 August ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the stea ...

Steam Frigates Of The Royal Netherlands Navy
Steam is a substance containing water in the gas phase, and sometimes also an aerosol of liquid water droplets, or air. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Steam that is saturated or superheated is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapor condenses. Water increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into mechanical work by steam engines such as reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapor pressure, it can create a steam explosion. Typ ...
