Sea Watch
At sea, the mate on watch has three fundamental duties: navigate the ship, safely avoid traffic, and respond to any emergencies that may arise. Mates generally stand watch with able seamen who act as helmsman and lookout. The helmsman executes turns and the lookout reports dangers such as approaching ships. These roles are often combined to a single helmsman/lookout and, under some circumstances, are eliminated completely. The ability to smartly handle a ship is key to safe watchstanding. A ship's draught, trim, speed and under-keel clearance all affect its turning radius and stopping distance. Other factors include the effects of wind and current, squat, shallow water and similar effects. Shiphandling is key when the need arises to rescue a man overboard, to anchor, or to moor the ship.
The officer must also be able to transmit and receive signals by Morse light and to use the International Code of Signals.

Famous quotes containing the words sea and/or watch:
“The only sin is limitation. As soon as you once come up with a man’s limitations, it is all over with him. Has he talents? has he enterprise? has he knowledge? It boots not. Infinitely alluring and attractive was he to you yesterday, a great hope, a sea to swim in; now, you have found his shores, found it a pond, and you care not if you never see it again.”
—Ralph Waldo Emerson (1803–1882)
“Eyes—the head’s chief of police. They watch and make mental notes. A blind person is like a city abandoned by the authorities. On sad days they cry. In these carefree times they weep only from tender emotions.”
—Anton Pavlovich Chekhov (1860–1904)
