Early first rates had as few as 60 guns, but by the mid-1660s they generally carried between 90 and 100 guns. By the early years of the 18th century, it had become accepted that 100 guns was the standard criterion for a first rate in wartime (while 90 guns, later 98 guns, became the standard wartime ordnance for a second rate). (In peacetime, all ships of the line carried a reduced complement of guns.) Towards the close of the century, ships were built with more than 100 guns, and they too were classed as first rates.
