Quick Summary
The mainmast is a sailing ship's principal mast. Historically, ships evolved from single-masted vessels to those with multiple masts to improve maneuverability and speed. By the 15th century, ships began to carry additional masts, and by the end of that century, large vessels could have three or four masts, each carrying sails. The arrangement and naming of masts, such as the foremast, mainmast, and mizzenmast, are important for setting sails and determining their function.123
