First, imagine the guy who came up with earliest elongated drinking vessel. Now try to figure out why the glassblower decided to call it a yard. Maybe he was attempting to speak Pirate, but instead of Yarg, he accidentally said Yard, and it stuck. A full yard holds three pints, certainly a creditable amount for any pirate worth his saltwater. Our 32-oz. half-yard is made of durable PVC plastic.
