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 Canada-class ships of the line were a series of four 74-gun third rates designed for the Royal Navy by William Bateley. The name ship of the class was launched in 1765.
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 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 Exeter-class ships of the line were a class of four 64-gun third rates, designed for the Royal Navy by William Bateley.
The Ardent-class ships of the line were a class of seven 64-gun third rates, designed for the Royal Navy by Sir Thomas Slade.
The Culloden-class ships of the line were a class of eight 74-gun third rates, designed for the Royal Navy by Sir Thomas Slade. The Cullodens were the last class of 74s which Slade designed before his death in 1771.
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 Courageux-class ships of the line were a class of six 74-gun third rates of the Royal Navy. Their design was a direct copy of the French ship Courageux, captured in 1761 by HMS Bellona. This class of ship is sometimes referred to as the Leviathan class. A further two ships of the class were built to a slightly lengthened version of the Courageux draught. A final two ships were ordered to a third modification of the draught.
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 Mars-class ships of the line were a class of two 74-gun third rates of the large class ships of the line, designed for the Royal Navy by Sir John Henslow.
The Ajax-class ships of the line were a class of two 74-gun third rates of the Royal Navy. They were grouped in with the large class of 74s, as they carried 24-pounders on their upper gun decks, rather than the 18-pounders of the middling and common class 74s. The design of the Ajax class was a lengthened version of the Valiant class, the lines of which were taken from the French Invincible, captured in 1747.
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 Black Prince-class ships of the line were a class of four 74-gun third rates built for the Royal Navy in the closing years of the Napoleonic War. The draught for this class of ship was essentially a reduced version of the captured Danish ship Christian VII.
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 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 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 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.
