Sail battleship refers to an armed ship that has been the main battle at sea since the 17th century, and generally has a multi-layer artillery deck. Sailing warships before 1840 were basically made of wood, sometimes covered with copper skin below the waterline.

The power of this warship is sail, and the weapon is muzzle gun. Generally, solid round projectiles are fired to destroy the hull, as well as killing shotguns and chain bombs to destroy the sails. At that time, because the power was driven by wind, the power range of single-ship artillery was not enough to cause effective damage to an enemy ship, so the battle line was adopted (all combat warships lined up in a line), so it was a standard combat mode, so Yun Fengfan battleships. Although the windsurfing battleship has many shortcomings, it is the main ship of the navy in the 17- 19 century, and it once dominated the sea for more than two centuries.
