The Sailor Tankard is used to hold Grog. Players can fill their tankard at the Tavern on Outposts. The Sailor Tankard is the first tankard available to players and is available in the Equipment Chest. Players can equip it using their radial menu.
If you drink enough grog then this could possibly look like a decente tankard.
