A lateen (from French latine, meaning "Latin") or latin-rig is a triangular sail set on a long yard mounted at an angle on the mast, and running in a fore-and-aft direction. Dating back to Roman navigation, the lateen became the favourite sail of the Age of Discovery. It is common in the Mediterranean, the upper Nile River, and the northwestern parts of the Indian Ocean, where it is the standard rig for feluccas and dhows. The lateen is used today in a slightly different form on small recreational boats like the highly popular Sailfish and Sunfish, but is still used as a working rig by coastal fishermen in the Mediterranean.
