General Duties of the QMOW, Continued
Maintaining
As you now know, maintaining the Ship’s Deck Log is a big part of the
Logs
QMOW’s duties. You must also maintain the following records:
Magnetic Compass Record Book
Standard Bearing Book
Weather observation sheets
Passdown log
The Magnetic Compass Record Book must be filled in each time the
ship changes course and on the hour and every l/2 hour as explained in
chapter 2. For example, if a ship changed course at 1947 an entry
would be made. The next entry would be 2000 and 2030, and so on
until the next course change. Gyrocompass error is entered in the
remarks column each time it is computed.
The Standard Bearing Book is used to record bearing, range, and
location of ATONs or radar points used to fix the ship’s position, during
piloting. Remember to enter the latitude and longitude of every ATON
or radar point used to fix the ship’s position beginning on the inside of
the back cover or as directed by the navigator.
As you learned in chapter 10, weather observation must be made each
hour whenever a ship is under way. You should begin your
observations about 15 minutes before the hour. This allows you to
completely record the observation data on the weather observation sheets
prior to obtaining the hourly fix of the ship’s position.
The passdown log is used to pass pertinent information down from
watch to watch. Make sure to record any information passed down to
you that concerns any aspect of the watch.
Plotting to
support
Weapons
During some operations, you may be required to maintain a plot in
support of live firing exercises. Maps that use a grid system of
coordinates are used to maintain the plot. This type of plotting requires
specialized training involving both OSs and QMs and is scheduled by
the Operations Department. The OSs maintain the manuals and
instruction that give complete information on his topic.
