A Ship's doctor or Ship's surgeon (frequently also called a Navy surgeon or Naval surgeon) is the person responsible for the health of the people aboard a ship at sea. The term "ship's doctor" or "ship's surgeon" appears often in reference to the British Royal Navy's "surgeons" during the Age of Sail. These men, like other physicians, often did not have much medical training. They cared for the members of the ship, dealing with wounds from battle, disease and the other medical problems which plagued the Royal Navy throughout the world.
