In the Age of Sail, there was a large variety of terms to describe sailing vessels. In British English, the meaning of the term 'sloop' depends on the context. The main source of confusion about the term sloop, is that for commercial vessels, 'sloop' referred and refers to a vessel with a single mast rigged fore-and-aft. [2] If the term referred to a British warship, its meaning was heavily dependent on the number of officers and men on the vessel. Under the rating system of the Royal Navy, any vessel that did not require a post-captain as commander, was a sloop. This generally referred to all vessels with less than 20 guns. By this system, small frigates that lost most of their guns and sailors so they could be used as transports, would be reclassified as sloops. The same logic also applied to fireships, which were typically made by converting fifth or sixth rate ships. [3]
In the late 17th century, sloops were generally ketch-rigged bomb vessels or generally ship-rigged fireships. After the start of the Seven Years' War in 1756, the majority of sloop was designed to have three masts. [4]
Steam vessels driven by propellers were differentiated from those driven by paddle-wheels by referring to the ship's screws (propellers). [5] Other propeller-driven warships included the heavier steam corvette and the ligther gun vessel.
By 1833, the Royal Navy's vessels fell in three classes: [6] [7]
At the time sloops could be ships (three masted) or brigs (two masts [8] ) or be corvette (also three masts) built or otherwise. [9] The term sloop referred to a sailing vessel. Small paddle steamers like HMS Rhadamanthus, [10] Meteor, [11] and Firebrand [12] were listed as 'steam vessels'.
In 1840, the steam vessels of the Royal Navy were also divided into classes: [13]
By 1845, the List of the Royal Navy referred to dozens of 'steam sloops'. Most of these were commanded by a commander, many others had a lieutenant commander. [14] Cyclops was still a steam frigate. Gorgon was now a steam sloop commanded by a captain. Hydra was a steam sloop. Meteor was a steam vessel.
In 1845 the first screw sloop appeared in the Royal Navy. The first four Alecto-class sloops had been launched in 1839-1841. The fifth unit of this class; Rattler was reordered as a screw propelled vessel. In Spring 1845 comparative trials were held between Rattler and Alecto. The most famous of these was that in which the sloops towed stern to stern, with Rattler towing Alecto backwards at 2.8 knots per hour. [15]
In the 1860s American context, the general meaning of the word 'sloop' was: A three masted square-rigged ship with a full broadside on a single deck. In a more loose sense, it could also refer to a three-mast vessel like CSS Alabama, which was a barque and lacked a full broadside. [5]
USS Princeton launched in September 1843, was the first world's screw steam vessel of war. [16] She had been designed by John Ericsson, who had previously applied the screw to commercial boats. Princeton was also revolutionary, because it had its engines under the waterline, and had an armament that included a very high caliber wrought iron gun. This gun proved able to penetrate 4.5 inches of armor. The success of Princeton led the United States Navy to slowly shift to the propeller as means of propulsion. [16]
In 1857 the United States ordered 5 large screw sloops. USS Hartford was a good example of these. [1] Brooklyn also belonged to this order that made the screw sloop popular. [17] In 1858 seven smaller screw sloops were ordered. USS Mohican and Narragansett were examples of these seven. [1]
A brig is a type of sailing vessel defined by its rig: two masts which are both square-rigged. Brigs originated in the second half of the 18th century and were a common type of smaller merchant vessel or warship from then until the latter part of the 19th century. In commercial use, they were gradually replaced by fore-and-aft rigged vessels such as schooners, as owners sought to reduce crew costs by having rigs that could be handled by fewer men. In Royal Navy use, brigs were retained for training use when the battle fleets consisted almost entirely of iron-hulled steamships.
In the 18th century and most of the 19th, a sloop-of-war in the Royal Navy was a warship with a single gun deck that carried up to eighteen guns. The rating system covered all vessels with 20 guns and above; thus, the term sloop-of-war encompassed all the unrated combat vessels, including the very small gun-brigs and cutters. In technical terms, even the more specialised bomb vessels and fireships were classed as sloops-of-war, and in practice these were employed in the sloop role when not carrying out their specialised functions.
Steam 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. The first such ships were paddle steamers. Later on the invention of screw propulsion enabled construction of screw-powered versions of the traditional frigates, corvettes, sloops and gunboats.
HMS Rattler was a 9-gun steam screw sloop of the Royal Navy, and one of the first British warships to be completed with screw propulsion. She was originally ordered as a paddle wheel 4-gun steam vessel from Sheerness Dockyard on 12 March 1841. She was reordered on 24 February 1842 as a propeller type 9-gun sloop from HM Royal Dockyard, Sheerness, as a new vessel. William Symonds had redesigned the ship as a screw propeller driven vessel.
Demologos was the first warship to be propelled by a steam engine. She was a wooden floating battery built to defend New York Harbor from the Royal Navy during the War of 1812. The vessel was designed to a unique pattern by Robert Fulton, and was renamed Fulton after his death. Because of the prompt end of the war, Demologos never saw action, and no other ship like her was built.
HMS Ardent was a wooden Alecto-class paddle sloop, and the fourth ship of the Royal Navy to use the name. She was launched on 12 February 1841 at Chatham and spent much of her career on the West Coast of Africa engaged in anti-slavery operations. One of the ship's company, Gunner John Robarts, was awarded the Victoria Cross for the destruction of Russian food stores in the Crimean War. She was scrapped in 1865.
HMS Melita was a Royal Navy Mariner-class composite screw sloop of 8 guns, launched in 1888 and commissioned in 1892. She was the only significant Royal Navy warship ever to be built in Malta Dockyard, She was renamed HMS Ringdove in 1915 as a salvage vessel and in 1920 was sold to the Falmouth Docks Company, which changed her name to Ringdove's Aid. She was sold again in 1926 to the Liverpool & Glasgow Salvage Association, renamed Restorer, and finally broken up in 1937, 54 years after her keel was laid.
HMS Niger was originally slated to be built as a Sampson designed sloop; however, she was ordered as a First-Class sloop with screw propulsion on 20 February 1845 to be built at Woolwich Dockyard, along the design developed by Oliver Lang and with a hull like the Basilisk designed paddle sloops. Her armament and engine were to be like the Encounter Design building at Pembroke. A second vessel (Florentia) was ordered on 26 March 1846 but after her keel was laid at Pembroke Dockyard, her construction was suspended on 6 October 1846 then cancelled three years later, on 22 May 1849. Niger She conducted important propulsion trials, finally proving the superiority of screw propulsion and served in West Africa, the Crimea, China, the East Indies and Australia. She took part in the New Zealand wars in 1860 and was sold for breaking in 1869.
HMS Cordelia was an 11-gun Racer-class sloop of the Royal Navy launched in 1856 and sold in 1870.
HMS Salamander was one of the initial steam powered vessels built for the Royal Navy. On 10 January 1831 the First Sea Lord gave orders that four paddle vessels be built to competitive designs. The vessels were to be powered by Maudslay, Son & Field steam engines, carry a schooner rig and mount one or two 10-inch shell guns. Initially classed simply as a steam vessel (SV), she was re-classed as a second-class steam sloop when that categorization was introduced on 31 May 1844. Designed by Joseph Seaton, the Master Shipwright of Sheerness, she was initially slated to be built in Portsmouth, and was changed to Sheerness Dockyard. She was launched and completed in 1832, took part in the Second Anglo-Burmese War and was broken up in 1883.
HMS Phoenix was a 6-gun steam paddle vessel of the Royal Navy, built in a dry dock at Chatham in 1832. She was reclassified as a second-class paddle sloop before being rebuilt as a 10-gun screw sloop in 1844–45. She was fitted as an Arctic storeship in 1851 and sold for breaking in 1864.
HMS Basilisk was a first-class paddle sloop of the Royal Navy, built at the Woolwich Dockyard and launched on 22 August 1848.
HMS Dee was the first paddle steamer ordered for the Royal Navy, designed to carry a significant armament. She was ordered on 4 April 1827 from Woolwich Dockyard. She was designed by Sir Robert Seppings, Surveyor of the Navy and modified by Oliver Lang. This vessel was considered as new construction as a previous vessel ordered as a flush deck Cherokee-class brig in 1824, had been renamed African in May 1825. She was initially classed as a steam vessel (SV), and in 1837 reclassified as a steam vessel class 2 (SV2). She was converted to a troopship in May 1842 and as a second class sloop in 1846. She was converted into a storeship in 1868. She was broken at Sheerness in 1871.
HMS Dwarf was launched in 1840 as the mercantile Mermaid. The Royal Navy purchased her in 1843 as the Navy's first screw-propelled vessel. She was broken up in 1853.
This glossary defines the various types of ships and accessory watercraft that have been used in service of the United States. Such service is mainly defined as military vessels used in the United States Navy and United States Coast Guard, as well as the defunct, incorporated, or renamed institutions such as the United States Revenue Cutter Service. Service of the United States can also be defined in this context as special government missions in the form of expeditions, such as the Wilkes Expedition or the North Pacific Exploring and Surveying Expedition. The scope of the glossary encompasses both the "Old Navy" of the United States, from its beginnings as the "Continental Navy", through the "New Navy" and up to modern day. The watercraft included in the glossary are derived from United States ships with logbooks published by the National Archives and Records Administration.
HMS Rhadamanthus was one of the initial steam powered vessels built for the Royal Navy. On 10 January 1831 the First Sea Lord gave orders that four paddle vessels be built to competitive designs. The vessels were to be powered by Maudslay, Son & Field steam engines, carry a schooner rig and mount one or two 10-inch shell guns. Initially classed simply as a steam vessel (SV), she was re-classed as a second-class steam sloop in 1846. Designed by Thomas Roberts, the Master Shipwright of Plymouth. She was launched and completed in 1832, She was converted into a transport in 1841 then in 1851 she was a troopship and by the 1860s she was a transport again. Her breaking was completed in February 1864.
HMS Medea was one of the initial steam-powered vessels built for the Royal Navy. On 10 January 1831 the new First Lord Sir James Graham, 2nd Baronet gave orders that four paddle vessels be built to competitive designs. The vessels were to be powered by Maudslay, Son & Field steam engines, carry a schooner rig and mount one or two 10-inch shell guns. Initially classed simply as a steam vessel (SV), she was re-classed as a second-class steam sloop when that categorization was introduced on 31 May 1844. Designed by Oliver Lang, the master shipwright of Woolwich. She was launched and completed in 1834, took part in the Syrian Coast Campaign and was broken up in 1867.
The Alecto-class steam vessels (SV3) later reclassed as Third Class Sloops, were designed by Sir William Symonds, the Surveyor of the Navy. The design was approved on 12 April 1839. Initially four vessels were ordered and completed. A fifth unit was ordered (Rattler), but was reordered as a screw propelled vessel. And a sixth unit had been ordered but was requested to be reordered to a different design. The screw driven Rattler participated in the first of three 'tug o- wars with the Alecto. The vessels all participated during the Russian War. All had gone to the breakers by the mid-1860s.
HMS Alecto was an Alecto-class sloop designed by Sir William Symonds, Surveyor of the Navy. Originally classed as a steam vessel (SV3), her classification would be changed to a Third Class Sloop. She initially served in the Mediterranean, prior to her tug of war with the Rattler. She spent her time in the Americas and mainly on the anti-slavery patrol off the west coast of Africa. She was broken in November 1865
