Xebecs were three-masted sailing ships that were popular in the Mediterranean during the 18th and 19th centuries. They were used for trading, fishing, and warfare, and were characterized by their long overhangs at both the bow and stern. Xebecs had a distinctive hull shape, with a sharp bow and a rounded stern, and were propelled by both oars and sails. They were also equipped with a lateen sail, which allowed them to tack against the wind.
