Quartermaster (Ship)
The Quartermaster (Ship) is second only to the Chief of the Boat amongst Enlisted personnel on a ship.
The Quartermaster is the enlisted member in charge of the watch-to-watch navigation and the maintenance, correction, and preparation of nautical charts and navigation publications. He is also responsible for navigational instruments and clocks and the training of ship's lookouts and helmsmen. He performs these duties under the control of the ship's navigator or other officer if there was no officer navigator.
The job of a quartermaster is also responsible for electronic systems that deal with navigation, internal communications, atmosphere monitoring, and remote valve indication or manipulation.
The Quartermaster trains and supervises crewmen in Bridge operations, repairs, and protocols and sets the agenda for instruction in general ship operations for the Boatswain's Mate; duty assignments for all Bridge personnel; may assume any Bridge or Operations role as required; and is qualified to temporarily act as Commanding Officer or Executive Officer if so ordered.
Quartermasters ensure that all officers and crew perform their duties consistent with Starfleet directives. The Quartermaster (Ship) reports to the Executive Officer.
While the Quartermaster is technically a member of the Operations departments, their job is closely related to Flight Control or Command.
NOTE: This position is not to be confused with Quartermaster (Starbase)
