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.
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.
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 Ramillies-class ships of the line were a class of nine 74-gun third rates, designed for the Royal Navy by Sir Thomas Slade.
The Alfred-class ships of the line were a class of four 74-gun third rates for the Royal Navy by Sir John Williams. They were an enlarged version of the Royal Oak class.
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 Caledonia-class ships of the line were a class of nine 120-gun first rates, designed for the Royal Navy by Sir William Rule. A tenth ship was ordered on 29 October 1827 to the same design, but was launched in 1833 as Queen to a fresh design by Sir William Symonds.
The Repulse-class ships of the line were a class of eleven 74-gun third rates, designed for the Royal Navy by Sir William Rule. The first three ships to this design were ordered in 1800, with a second batch of five following in 1805. The final three ships of the class were ordered towards the end of the Napoleonic War to a modified version of Rule's draught, using the new constructional system created by Sir Robert Seppings; all three were completed after the war's end.
The Téméraire-class ships of the line were a class of a hundred and twenty 74-gun ships of the line ordered between 1782 and 1813 for the French navy or its attached navies in dependent (French-occupied) territories. Although a few of these were cancelled, the type was and remains the most numerous class of capital ship ever built to a single design.
The Canopus-class ships of the line were a class of nine 84-gun two-deck second rates of the Royal Navy. Their design was based on an enlarged version of the lines of the captured French ship Franklin, since commissioned in the Royal Navy as HMS Canopus, although this ship herself was not included as a member of the class. The earlier ships were initially ordered as 80-gun third rates, but this classification was altered by changes in the rating system in February 1817. This class of ships is sometimes referred to as the Formidable class.
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 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 Apollo-class sailing frigates were a series of twenty-seven ships that the British Admiralty commissioned be built to a 1798 design by Sir William Rule. Twenty-five served in the Royal Navy during the Napoleonic Wars, two being launched too late.
The Scamander class sailing frigates were a series of ten 36-gun ships, all built by contract with private shipbuilders to an 1812 design by Sir William Rule, which served in the Royal Navy during the late Napoleonic War and War of 1812.
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.
