The quartermaster ranked higher than any other officer aboard the ship except the captain himself, and could veto the captain's decisions whenever the ship was not chasing a prize or engaged in battle. The quartermaster also was chiefly responsible for discipline, assessing punishments for crewmen who transgressed the articles. Several quartermasters, notably among them Calico Jack Rackham, became captains after their previous captain was killed or deposed.
