A galleass was a warship that combined the sails and armament of a galleon with the maneuverability of the oared galley.Relatively few galleasses were built—one disadvantage was that, being more reliant on sails, their position at the front of the galley line at the start of a battle could not be guaranteed.[5] Four great Naples galleasses were deemed sufficiently seaworthy to accompany the Spanish Armada in 1588 (e.g. La Girona, eventually wrecked off Ireland), where they formed part of the front-line of fighting ships.[6] During the Channel actions, they were repeatedly called on as a squad in any calm, to rescue Spanish stragglers or cut-off a stray English ship.[8] In the Mediterranean, with its less dangerous weather and fickle winds, both galleasses and galleys continued to be in use, particularly in Venice and the Ottoman Empire, long after they became obsolete elsewhere.
