A sailor or mariner is a person who navigates water-borne vessels
or assists in their operation, maintenance, or service. The term can
apply to professional mariners, military personnel, and recreational
sailors as well as a plethora of other uses. Etymologically, the
name preserves the memory of the time when ships were commonly
powered by sails, but applies to the personnel of all vessels,
whatever their mode of locomotion.
Professional mariners hold a variety of professions and ranks which are fairly standard, with the exception of slight naming differences around the world. Common categories by department include the Deck department, the Engineering department, and the Steward's department. Mariners can also be categorized by status as a senior licensed mariners or unlicensed mariners.
