Fourth-rate

rdf:langString Fourth-rate

rdf:langString In 1603 all English warships with a compliment of fewer than 160 men were known as 'small ships'. In 1625/26 to establish pay rates for officers a six tier naval ship rating system was introduced. These small ships were divided into three tiers, Fourth, Fifth and Sixth rates. Up to the end of the 17th century the number of guns and the compliment size was adjusted until the rating system was actually clarified. A 'Fourth Rate' was nominally a ship of over thirty guns with a complement of 140 men. In the rating system of the Royal Navy used to categorize sailing warships in the 18th century, a fourth-rate was a ship of the line with 46 to 60 guns mounted. They were phased out of ship of the line service during the French Revolutionary and Napoleonic Wars, as their usefulness was declining; though they were still in service, especially on distant stations such as the East Indies. Fourth-rates took many forms, initially as small two decked warships, later as large frigates razéed from the initial two deck warships, and occasionally even heavily armed merchant ships such as HMS Calcutta.
