The sail is usually canted rectangular sail or lateen sail. These technologies include the plank-sewn hulls, catamarans, outrigger boats, and possibly the lateen sail. This rig was a loose footed lateen sail hung from a centered mast. The ship carried one mast with a lateen sail for better maneuvering. Locally built traditional lateen sail fishing boats (luggers) can be spotted in the harbour. The lateen sail proved to have better upwind performance for smaller vessels. Likewise, lateen sail survived in the Baltic until the late 19th century. The lateen sail originated somewhat later during the Roman empire in the Mediterranean Sea.
