| Watch | 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; also refers to those standing watch as an individual, pair, or group. In order to prevent the same men from keeping the same watch each day, the watch between 1600 and 2000 is divided into two half watches, known as the first and last dog watches, in order to produce an odd number of watches each day. |
