Watch, английский
- A period of time during which a part of the crew is on duty. changes of watch are marked by strokes on the ship`s bell.
- The day at sea is divided into six four hour periods. three groups of watchstanders are on duty for four hours and then off for eight, then back to duty. seamen often work overtime during their off time.
- Вахта
- The division of the ship`s company into two parties, one called the starboard, and the other the larboard or port watch, alluding to the situation of their hammocks when hung up; these two watches are, however, separated into two others, a first and second part of each, making four in all. the crew can also be divided into three watches. the officers are divided into three watches, in order to lighten their duty; but it is to be borne in mind that the watch may sleep when their services are not demanded, whereas it is a crime, liable to death, for an officer to sleep on his watch. in a ship of war the watch is generally commanded by a lieutenant, and in merchant ships by one of the mates. the word is also applied to the time during which the watch remains on deck, usually four hours, with the exception of the dog-watches.—anchor-watch. a quarter watch kept on deck while the ship rides at single anchor, or remains temporarily in port.—dog-watches. the two reliefs which take place between 4 and 8 o`clock p.m., each of which continues only two hours, the intention being to change the turn of the night-watch every twenty-four hours.—first watch. from 8 p.m. till midnight.— middle-watch. from midnight till 4 a.m.—morning-watch. from 4 to 8 a.m.—watch is also a word used in throwing the deep-sea lead, when each man, on letting go the last turn of line in his hand, calls to the next abaft him, “watch, there, watch!” a buoy is said to watch when it floats on the surface of the water.
- [1] one of the divisions of the nautical day as outlined below. [2] the members of a ship’s company assigned to duty during such a division. [3] a spell of duty. it is inconceivable that an oceangoing ship could be operated around-the-clock without shift work and, from the earliest days of navigation there are records showing the division of crews into groups known as watches. nowadays, the merchantman’s nautical day is most usually divided into six 4-hour time periods, but sometime follow the warship routine of five 4-hour and two 2-hour watches. the shorter periods—called “dogwatches”—ensure that seamen are not always on duty at the same time, whether the crew is divided into the usual three watches, which gives them eight hours between spells of duty, or in two (watchand- watch) standing a grueling four hours on and four off. the term originated in the 17th century and is of uncertain origin, though some say it is a corruption of “dodge watch.” british and u.s. watch terminology are slightly different: in the usn, normal bell routine continues through the dogwatches, with 1, 2, 3, 4 bells being rung in the first and 5, 6, 7, 8 in the second. the rn also rings 1, 2, 3, 4 bells in the first dogwatch, but 1, 2, 3, 8 in the last. this originated on 13th may 1797, when officers learned that five bells instead of four in the last dogwatch was to be the signal for launching a mutiny. see also “five and dimes.” watch-and-watch: a watch bill based on only two duty sections, so that each has only four hours for eating, sleeping, and recreation before the next spell of duty. this arduous schedule has also been called fouron- four-off, heel-and-toe, turn-and-turn, and watchand- watch-about. the most usual naval terminology is port-and-starboard watches.
- A4 hour duty period while at sea.
