Polacca
（重定向自Polacre）
A polacca (or polacre) is a type of seventeenth-century sailing vessel, similar to the xebec. The name is the feminine of "Polish" in the Italian language. The polacca was frequently seen in the Mediterranean. It had two or three single-pole masts, the three-masted vessels often with a lateen hoisted on the foremast (which was slanted forward to accommodate the large lateen yard) and a gaff or lateen on the mizzen mast. The mainmast was square-rigged after the European style. Special polaccas were used by Murat Reis, whose ships had lateen sails in front and Fore-and-aft rig behind.
