Watch

 

Basic type of duty on ships and vessels, for the purpose of maintaining their combat readiness (in the navy) and navigational safety. The watch on naval ships is divided into general ship’s watch (combat watch, bridge watch at sea, and anchor watch) and special (for example, engine-crew watch). The distribution of personnel in shifts is provided for in special rosters. The term “watch” is also used to designate the interval of time during which one shift of a 24-hour detail stands watch; its duration is not more than six hours. The most difficult watch is considered to be the first night watch from 0:01 to 4:00 hours, which is called the dogwatch in all the navies of the world.

(2) Obsolete term used to designate half of the crew of a ship (vessel). Up until the 19th century a ship’s crew was divided into two watches; the first watch was located (hung its hammocks) in the right-hand portion of the ship’s hull and the second watch, in the left portion.
