简介：Originally, Western shipbuilding technology lagged behind the East, but the emergence of three-masted sailing ships changed this. The three-masted sailing ship has three masts and a more reasonable hull structure. It can use the wind within an angle of 65 degrees to travel. Because the hull is huge, it can carry a large amount of daily necessities. It can sail at sea for several months and even sail around the earth.
