Captain

A captain is the person invested with operational command of a ship — the holder of the ship’s command office, bearing absolute authority aboard within the bounds of the ship’s charter. The captain’s authority is delegated, bounded, and revocable: delegated by the commissioning authority that chartered the ship, bounded by the charter’s terms, and revocable by the commissioning authority without dissolving the ship.

The word comes from Late Latin capitaneus, from caput (head). The captain is the head of the venture — the single point of operational decision. This is not metaphor. In admiralty law, the master of a vessel holds authority that no other person aboard can override, countermand, or share. Thomas Joseph Schoenbaum’s Admiralty and Maritime Law (5th ed., 2011) states the doctrine plainly: the master’s authority is “absolute and unqualified” in matters of navigation, safety, and the prosecution of the voyage. The crew obeys; the passengers comply; the cargo is the master’s charge.
