Descripción:
A single square sail was very popular among many of the ships built before the 9th century. This lateen sail was seen by Byzantine naval forces in the 6th century but never caught on until the 9th. With the lateen sails having a triangle shape about them they can allow ships to sail into the wind.Añadido al timeline:
