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 Boyne-class ships of the line were a class of two 98-gun second rates, ordered in 1783 and designed for the Royal Navy by Sir Edward Hunt.
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 Nelson-class ships of the line were a class of three 120-gun first rates, designed for the Royal Navy as a joint effort between the two Surveyors of the Navy at the time.
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 Lively class were a successful class of sixteen British Royal Navy 38-gun sailing frigates.
The Burford class ships were three 68-gun third rates designed for the Royal Navy by Sir Joseph Allin. The Burford ships were almost the last "70-gun" ships designed by Allin. They were built to the draught specified by the 1745 Establishment as amended in 1754.
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 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.
