galleass

A galleass was a warship of the Renaissance that combined the sails and armament of a galleon or carrack with the propulsion and maneuverability of the oared galley. While never quite matching up to the full expectations for its design, the galleass was widely employed by the navies of the Republic of Venice and the Spanish Empire during the 16th and 17th centuries.
