This rank is also used by many other navies based on the French Navy. Norwegian Navy In the Norwegian navy, quartermaster is a rank equal to an army sergeant. United States U.S. Navy 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. They are also responsible for navigational instruments and clocks and the training of ship's lookouts and helmsmen. They perform these duties under the control of the ship's navigator or other officer if there was no officer navigator. In the modern navy, a quartermaster is a petty officer who specializes in navigation. The rating abbreviation is QM. The symbol used for the rating and worn on uniforms is a ship's wheel. The colloquial form of address for a quartermaster is "Wheels". On U.S. Navy submarines, the job of a quartermaster is done by a qualified navigation electronics technician (NAV-ET). Along with the job of a Navy surface QM, NAV-ETs are also responsible for electronic systems that deal with navigation, internal communications, atmosphere monitoring, ship's entertainment systems, re-circulatory air systems (ventilation) and remote valve indication or manipulation. After 2004, the U.S. Navy disestablished the signalman rating (SM); signalmen were responsible for visual communications, and many of the personnel and their responsibilities were incorporated in the QM rating. The U.S. Navy rating dealing with supply and logistics is logistics specialist (LS) which would be equivalent to the Army quartermaster.

The Coast Guard used a quartermaster rating until the summer of 2003, when the rating was merged into the boatswain's mate rating. The Coast Guard's quartermasters had the same duties as the Navy's, with the exception that—at some point after World War II—the Coast Guard folded the duties of its signalman rating into the quartermaster rating. Also, in recent decades, quartermaster was one of the only two Coast Guard enlisted ratings permitted to hold command of a small boat station (command otherwise being reserved for officers), with the other enlisted man's "command rating" being the boatswain's mate.

On pirate ships, the quartermaster was
