A lateen sail is a triangular sail set on a long yard mounted at an angle on the mast, running in a fore-and-aft direction. It's a key element of maritime history, known for its maneuverability. Think of it as the wing of a ship, catching the wind to propel it forward. Unlike square sails, lateen sails allow ships to sail closer to the wind. They were commonly used in the Mediterranean Sea and the Indian Ocean. The lateen sail is a historical innovation.
