Ship of the Line (Sailing Ship of the Line)

Timeline

1. 1661–1664London and Portsmouth · HampshireIn the 1660s, building on experience from the English Civil War, the British Royal Navy classified large sailing warships by tonnage and armament and formally adopted line-of-battle tactics: ships formed a column and suppressed the enemy fleet with broadside volleys. Dockyards at Portsmouth and elsewhere accelerated construction of second- and third-rate ships of the line.
2. 1665–1666Lowestoft and the North Foreland · Offshore NorfolkAt the Battle of Lowestoft in 1665 and the Four Days' Battle and St. James's Day Battle in 1666, the English and Dutch each fielded dozens of ships of the line in line-of-battle engagements. These battles validated the feasibility of line tactics while exposing shortcomings in command coordination and fire-control accuracy, prompting both nations to accelerate construction of ships of the line with larger-caliber guns.
3. 1667–1670Rotterdam and Vlissingen · ZeelandBy 1670, both England and the Netherlands had designated 60–80-gun third-rate ships of the line as the backbone of their fleets. The Netherlands continuously launched standard ships of the line at naval ports such as Vlissingen, while England consolidated the size of its state fleet through the Navy Acts. The concept of the sailing ship of the line as an independent ship class was fully established in this period.
