The Deck Department is an organizational unit aboard naval and merchant ships. A ''Deck Officer'' is an officer serving in the deck department. ==Merchant shipping== The chief mate is the head of the deck department. This involves administrative tasks such as scheduling work, quality control, coordinating with other departments, and conflict resolution. The Chief Mate also compiles supply, overtime, and cost control records, and requisitions or purchases stores and equipment. Depending on the number of officers carried, he may or may not be a watch officer. If the ship carries a Second Mate and two Third Mates, he will be a dayworker, with a duty day from 0800 to 1700 ship's time. If only one Third Mate is carried, he will stand the 4 to 8 watch in addition to handling his executive duties. The ship's other deck officers, generally a Second Mate and Third Mate, are also members of the Deck Department. Each watchstanding officer is responsible for the unlicensed crewmen on his watch. In a four mate ship where the Chief Mate is a dayworker, the Second Mate will stand the 4 to 8 watch, because sunrise and sunset usually fall on that watch. In the days before satellite navigation systems, the Second Mate shot morning and evening star fixes to determine the ship's position. The Second Mate is also responsible for maintaining the ship's charts and navigational publications, the ship's gyrocompass, and all navigational gear. He also keeps the log extract for each voyage used by company management as a short form "howgozit" sheet, covering time at sea, time under pilotage, time in port, and types and tonnages of cargoes moved. The two Third Mates are often called the Senior Third and the Junior Third. The Senior Third Mate stands the 12 to 4 watch, the Junior Third the 8 to 12 watch. While on duty, they are responsible for handling the ship and fixing its position by shooting sun lines, taking hourly fixes from the satellite navigation gear, and piloting the ship in coastal waters; and the Senior Third will prepare the noon position slip for the use of the Captain and Chief Engineer. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Deck department」の詳細全文を読む スポンサード リンク
