Ship's Cook

Cook. A ship's cook works with the limited ingredients aboard a ship to make meals. A skilled cook keeps the crew's morale in top shape, while a poor one drags down the entire crew's performance. A talented cook has a high Constitution score, as well as proficiency with brewer's supplies and cook's utensils.

  Pirate ships did not have professional cooks. Usually, a just ordinary crewmember was in charge of food making.
