Spanish, French, Venetians, and even the British squadron in Gibratar used Xebecs extensively. Xebecs have a number of strong points compare to Frigates. Because they can swap their normal ship rigged sails for Lateen sails, Xebecs can sail much closer to the wind than square rigged Frigates. Xebec hull, being descended from rowling galleys, can be rowed much more efficiently then frigate hulls, so when the wind dies, a Xebec can row its way out of touble where as a Frigate would have to either sweep laboriously, or lower rowing boats to tow herself.
