WThe 64-gun ship of the line was a type of two-decker warship defined during the 18th century, named after the number of their guns. 64-guns had a lower battery of 24-pounders, and an upper battery of 12-pounders. Heavier variants with 18-pounder on the upper deck also existed.
WThe 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 first two were originally ordered in March 1840 as 80-gun ships of the Vanguard class, but were re-ordered to a new design of 90 guns some three months later. Three more ships to this design were ordered in March 1840, but two of these were re-ordered to fresh designs in 1847.
WThe 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.

HMS Bulwark and HMS Robust were kept on the stocks almost complete, in case of need, until they were scrapped in 1873 and 1872.
WThe 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.
WThe 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.
WThe 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.

A final two ships were ordered to a third modification of the draught.

A second batch of five ships was ordered in 1805 to a slightly further modified version of the original draught.

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.
WThe London class ships of the line were a class of four second rates, designed for the Royal Navy by Sir Thomas Slade.

WThe 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 class comprised Sultan Makhmud, Trekh Ierarkhov, Arkhangel Gavriil, Selafail, Uriil, Varna, Iagudiil, and Sviatoslav. They were built as part of a naval expansion program directed against the British and French, which Russia viewed as competitors to fill the power vacuum left by the continued decline of the Ottoman Empire. The ships represented an improvement over the traditional seventy-four, as improved building techniques allowed naval designers to build larger, more heavily armed vessels without sacrificing the hull strength that had made the seventy-fours such effective warships.
WThe Swiftsure-class ships of the line were a class of two 74-gun third rates, designed for the Royal Navy by Sir John Henslow.
WThe Valiant-class ships of the line were a class of two 74-gun third rates of the Royal Navy.

WThe Vengeur-class ships of the line were a class of forty 74-gun third rates, designed for the Royal Navy as a joint effort between the Surveyors of the Navy at the time. The Vengeur Class, sometimes referred to as the Surveyors' class of third rates, amongst other names, was the most numerous class of ships of the line ever built for the Royal Navy - forty ships being completed to this design. Due to some dubious practices, primarily in the commercial dockyards used for construction, this class of ships earned itself the nickname of 'Forty Thieves.'
WThe Worcester-class ships of the line were a class of three 64-gun third rates, designed for the Royal Navy by Sir Thomas Slade.
