Boxhaul is a nautical term that refers to the act of turning a ship's head to windward and then bringing it back on the opposite tack to resume its original course. Synonyms for boxhaul include wearing ship, tacking, changing tack, and coming about. All of these expressions involve altering the ship's heading in a deliberate fashion, often to overcome unfavorable winds or currents. Other related terms in the maritime lexicon include jibe, which refers to turning the ship's stern through the wind, and gybe, which is similar to a jibe but involves more radical changes in direction. Whatever the context, these maneuvers require skill, strength, and agility on the part of the crew.
