The Coventry-class frigates were 28-gun sixth rate frigates of the Royal Navy, principally in service during the Seven Years' War and the American Revolutionary War. They were designed in 1756 by Britain's Surveyor of the Navy, Sir Thomas Slade, and were largely modeled on HMS Tartar, which was regarded as an exemplar among small frigates due to its speed and maneuverability. The 1750s were a period of considerable experimentation in ship design, and Slade authorized individual builders to make "such alterations withinboard as may be judged necessary" in final construction.
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 Hercules class ships of the line were a class of two 74-gun third rates, designed for the Royal Navy by Sir Thomas Slade.
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 Sandwich class ships of the line were a class of three 90-gun second 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 Albion-class ships of the line were a class of five 74-gun third rates, designed for the Royal Navy by Sir Thomas Slade.
The Edgar-class ships of the line were a class of three 60-gun fourth 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 Ganges-class ships of the line were a class of six 74-gun third rates, designed for the Royal Navy by Sir Edward Hunt.
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 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 Neptune-class ships of the line were a class of three 98-gun second rates, designed for the Royal Navy by Sir John Henslow. All three of the ships in the class took part in the Battle of Trafalgar in 1805.
The Fame-class ships of the line were a class of four 74-gun third rates, designed for the Royal Navy by Sir John Henslow. After the name-ship of the class was ordered in October 1799, the design was slightly altered before the next three ships were ordered in February 1800. A second batch of five ships was ordered in 1805 to a slightly further modified version of the original draught.
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 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.
