Three-masted ships are sailing vessels that have three masts, which are tall poles that support the sails. These ships were commonly used from the 16th to the 19th centuries for trade, exploration, and naval warfare. The arrangement of sails on each mast allows for better maneuverability and speed, making them effective for long voyages across oceans. The design of three-masted ships includes various types, such as the barque, brig, and schooner. Each type has a unique sail configuration, which influences its handling and performance. These ships played a significant role in maritime history, facilitating global trade and exploration during the Age of Sail.
