''HSwMS Garmer'' was a small river monitor built for the Swedish Royal Skerry Artillery in the mid-1860s. She was designed to operate on the Swedish canals and lakes as well as in the shallow waters of the coast. The ship's captain had to steer the ship as well as aim and fire her gun. ''Garmer'' was sold for scrap in 1893. ==Design and description== In 1865 the Navy Minister, Baltzar J. van Platen, persuaded the Riksdag of the Estates to establish the Royal Skerry Artillery as part of the Swedish Army to defend the inner Swedish waters and protect the flanks of Swedish fortresses. This force was to be equipped with ten small monitors to operate in shallow waters that could navigate the Göta Canal system that linked Gothenburg ((スウェーデン語:Göteborg)) on the west coast to Söderköping on the Baltic Sea. HSwMS ''Garmer'', named after the dog Garmr from Norse mythology, was the first of these monitors. She was designed by the inventor John Ericsson and Lieutenant John Christian d'Ailly. ''Garmer'' was intended to support Karlsborg Fortress on Lake Vättern. A report to the Parliament of Sweden described her as lacking a keel, flat-bottomed amidships and had a sharp bow and stern. The ship measured long overall and had a beam of . She had a draft of and displaced . Her crew numbered 20 officers and men.〔Harris, pp. 28–29〕 ''Garmer'' had a single steam engine imported from New York that was powered by a single fire-tube boiler. The monitor had a maximum speed of , half a knot less than her designed speed of . She was armed with a single muzzle-loading M/66 smoothbore gun mounted in a long, fixed, oval-shaped turret. In 1877 ''Garmer'' received a 10-barreled M/75 machine gun〔 designed by Helge Palmcrantz. The machine gun weighed and had a rate of fire of 500 rounds per minute. Its projectiles had a muzzle velocity of and a maximum range of .〔Bojerud, pp. 177–78〕 ''Garmer'' had a complete waterline armor belt of wrought iron that was thick. The deck was thick. The gun turret's armor was on its face. The conning tower protruded from the top of the turret and was protected by of armor.〔Harris, p. 27〕 ''Garmer''s commander was rather overtasked as this excerpt explains: "The Commander is stationed inside a cupola and stands by the steering gear where he must control the vessel's movements at the same time as filling the touch hole and firing the gun. Sometimes there are difficulties with the engine. Since the gun is fixed, training is by the movement of the vessel."〔quoted in Harris, p. 28〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「HSwMS Garmer」の詳細全文を読む スポンサード リンク
