Lateen sails are triangular sails set on a long yard mounted at an angle on the mast. This design allows the sail to catch wind from various directions, making it particularly effective for sailing against the wind. Lateen sails were commonly used in the Mediterranean Sea and became popular in Arab and European maritime cultures. These sails are often associated with dhows, traditional sailing vessels used in the Indian Ocean and Red Sea. The lateen sail's shape and rigging enable better maneuverability and speed, contributing to the development of trade routes and exploration during the Age of Sail.
