Rating System of the Royal Navy

From PotBS Wiki

A system of categorization used by the British Royal Navy to classify ships in order of their effectiveness in line of battle based primarily on their number of guns from the late 17th century until the beginning of the 19th.

Note that when counting a ship's guns in order to determine her rating, swivel guns and carronades are not included - though bow and stern chasers are.
