Second-rate

In the rating system of the Royal Navy used to categorise sailing warships, a second-rate was a ship of the line which by the start of the 18th century mounted 90 to 98 guns on three gun decks; earlier 17th-century second-rates had fewer guns and were originally two-deckers or had only partially armed third gun decks. A "second-rate" was the second largest class of warships in a hierarchical system of six "ratings" based on size and firepower.

They were essentially smaller and hence cheaper versions of the 100-gun first-rates. Like the first rates, they fought in the line of battle, but unlike the first rates, which were considered too valuable to risk in distant stations, the second-rates often served also in major overseas stations as flagships. They had a reputation for poor handling and slow sailing. They were popular as flagships of admirals commanding the Windward and/or Leeward Islands station, which was usually a Rear-admiral of the red.
