A cabin boy or ship's boy is a boy (in the sense of low-ranking young male employee, not always a minor in the juridical sense) who waits on the officers and passengers of a ship, especially running errands for the captain.
Cabin boys were usually 13–16 years old, but sometimes as young as 8, and also helped the cook in the ship's kitchen and carried buckets of food from the ship's kitchen to the forecastle where the ordinary seamen ate. They would have to run from one end of the ship to the other tie knots. They would have to scramble up the rigging into the yards whenever the sails had to be trimmed. They would occasionally stand watch like other crewmen or act as helmsman in good weather, holding the wheel to keep the ship steady on her course.
