The "seventy-four" was a type of two-decked sailing ship of the line which nominally carried 74 guns. It was developed by the French navy in the 1740s and spread to the British Royal Navy where it was classed as third rate. From here, it spread to the Spanish, Dutch, Danish and Russian navies. The design was considered a good balance between firepower and sailing qualities, but more importantly, it was an appealing ideal for naval administrators and bureaucrats. Seventy-fours became a mainstay of the world's fleets into the early 19th century when they began to be supplanted by new designs and by the introduction of steam powered ironclads.
As a standard type, the seventy-four was only an ideal construction. There was great variation between seventy-fours of different navies. In the period 1750–1790, different ships could have displacements of anything at just under 2,000 tonnes up to 3,000 tonnes. The armament could also vary considerably with everything from 24-pounder to long 36-pounder guns and some seventy-four of the Danish navy actually only had 70 guns.
The first 74-gun ships were constructed by the French as they rebuilt their navy during the early years of the reign of Louis XV. The new ship type was a very large two-decker big enough to carry the largest common type of gun (36-pounders) on the lower gun deck, something only three-deckers had done earlier. This great firepower was combined with very good sailing qualities compared to both the taller three-deckers and the shorter old-style 70-gun two-deckers, making the 74 the perfect combination of the two. A disadvantage of the 74 was that it was relatively expensive to build and man compared to the older type of two-decker.
The 74-gun ship carried 28 (24-pounders- to 36-pounders) on the lower gun deck, 28–30 (18- to 24-pounders) on the upper gun deck, and 14–18 (6- to 12-pounders) on the upper works. Crew size was around 500 to 750 men depending on design, circumstances and nationality, with British ships tending to have smaller crews than other navies. The French had large and small seventy-fours, called "grand modèle" and "petite modèle", the waterline length of a "grand modèle" seventy-four could be up to 182 feet. This was copied by the Royal Navy in about two dozen such ships of its own, such as HMS Colossus where they were known as Large, while the other seventy-fours built to be between 166–171 feet (51–52 m) were known as Common.
