The Hecla class was a class of bomb vessels of the Royal Navy of the early 19th century. They were designed for use as bomb or mortar ships and were very heavily built. Eight ships were launched; all were converted for use as exploration or survey ships. Four ships of the class are known for the role they played in Arctic and Antarctic exploration.
HMS Hyacinth was an 18-gun Royal Navy ship sloop. She was launched in 1829 and surveyed the north-eastern coast of Australia under Francis Price Blackwood during the mid-1830s. She took part in the First Opium War, destroying, with HMS Volage, 29 Chinese junks. She became a coal hulk at Portland in 1860 and was broken up in 1871.
The Minerva-class sailing frigates were a series of four ships built to a 1778 design by Sir Edward Hunt, which served in the Royal Navy during the latter decades of the eighteenth century.
In 1794, three 64-gun third-rate ships were cut down to 44-gun fifth-rate frigates with a primary armament of 24-pounder guns, in a process known as razeeing. This was in response to rumours then circulating of very large French frigates supposed to be under construction. By Admiralty Order of 11 August 1794, two 64-gun ships of the Intrepid class – Anson and Magnanime – were to be cut down by one deck level. By a subsequent Admiralty Order of 8 September 1794, a third 64-gun ship – the Indefatigable of the Ardent class – which had been launched but never commissioned in 1784, was similarly to be cut down.
The Bellona-class ships of the line were a class of five 74-gun third rates, whose design for the Royal Navy by Sir Thomas Slade was approved on 31 January 1758. Three ships were ordered on 28 December 1757, with names being assigned on 1 February 1758. Two further ships to this design were ordered on 13 December 1758, at the same time as two ships of a revised design – the Arrogant class.
The Dublin-class ships of the line were a class of seven 74-gun third rates, designed for the Royal Navy by Sir Thomas Slade.
The Intrepid-class ships of the line were a class of fifteen 64-gun third rates, designed for the Royal Navy by Sir John Williams. His design, approved on 18 December 1765, was slightly smaller than Sir Thomas Slade's contemporary Worcester-class design of the same year, against which it was evaluated competitively. Following the prototype, four more ships were ordered in 1767–69, and a further ten between 1771 and 1779.
The Vanguard-class ships of the line were a class of two-deck 80-gun second rates, designed for the Royal Navy by Sir William Symonds, of which nine were completed as sailing ships of the line, although another two of these were completed as steam warships.
The Pallas-class frigates were a series of three frigates built to a 1791 design by John Henslow, which served in the Royal Navy during the French Revolutionary and Napoleonic Wars.
The Southampton-class frigates launched from 1820 onwards were 52-gun sailing frigates of the fourth rate produced for the Royal Navy following the close of the Napoleonic War. They were designed in 1816 to carry sixty guns, but were completed with fifty-two guns only. The design, a joint effort by the Surveyors of the Navy, was modified from that of the Java launched in 1815.
The Lively class were a successful class of sixteen British Royal Navy 38-gun sailing frigates.
The Bucentaure class was a class of 80-gun French ships of the line built to a design by Jacques-Noël Sané from 1802 onwards, of which at least 29 were ordered but only 21 ships were launched. They were a development from his earlier Tonnant class.
The Banterer-class sailing sixth rates were a series of six 22-gun post ships built to an 1805 design by Sir William Rule, which served in the Royal Navy during the Napoleonic War. The first four were launched in 1806 and the remaining two in 1807. One ship – the Banterer – was lost in 1808 and another – the Cyane – captured by the United States Navy in 1815; the remaining four were all deleted during 1816.
The Conway class sailing sixth rates were a series of ten Royal Navy post ships built to an 1812 design by Sir William Rule. All ten were ordered on 18 January 1812, and nine of these were launched during 1814, at the end of the Napoleonic War; the last (Tees) was delayed and was launched in 1817.
The Hermes class were a series of four 20-gun ships, launched between 1811 and 1816. Two pairs of ships were produced, to slightly different designs – the first two had 20 guns and were unrated flush-decked ship-sloops, whilst the latter two were converted to 26-gun sixth-rates. The design was based on the ex-French 20-gun corvette Bonne Citoyenne, which the British had captured in 1796.
The Seringapatam-class frigates, were a class of British Royal Navy 46-gun sailing frigates.
The Roebuck-class ship was a class of twenty 44-gun sailing two-decker warships of the Royal Navy. The class carried two complete decks of guns, a lower battery of 18-pounders and an upper battery of 9-pounders. This battery enabled the vessel to deliver a broadside of 285 pounds. Most were constructed for service during the American Revolutionary War but continued to serve thereafter. By 1793 five were still on the active list. Ten were hospital ships, troopships or storeships. As troopships or storeships they had the guns on their lower deck removed. Many of the vessels in the class survived to take part in the Napoleonic Wars. In all, maritime incidents claimed five ships in the class and war claimed three.
The Atholl-class corvettes were a series of fourteen Royal Navy sailing sixth-rate post ships built to an 1817 design by the Surveyors of the Navy. A further four ships ordered to this design were cancelled.
HMS Seahorse was a 44-gun Seringapatam-class fifth-rate frigate built for the Royal Navy during the 1820s, one of three ships of the Andromeda sub-class. After completion in 1830, she was ordered to be converted into a steam-powered ship in 1845, but this did not happen for another decade.
HMS Forth was a 44-gun Seringapatam-class fifth-rate frigate built for the Royal Navy during the 1820s, one of three ships of the Andromeda sub-class. After completion in 1833, she was ordered to be converted into a steam-powered ship in 1845, but this did not happen for another decade.
