Ancient sailing ships were made of wood, with a central mast holding a square sail, which used wind to propel the ship forward. In ancient times, people often used these ships to transport goods. Early warships had many masts, and when the sails were raised, they could generate strong driving force. By adjusting the triangular sail at the bow, warships could also sail against the wind. Early warships were equipped with long-range bronze cannons, giving them strong naval combat capabilities.
