The direction is towards Piloting in restricted Waters and over the horizon targeting. Celestrial is very miner. The new 08 Instr. gives on board of sextant, Almanac and reduction tables, but dropped the Days work in Navigation.
I will give you the QMOW duties that best show this. The OOD on most Naval ships are very busy with manuvering and other activities, The Senior QM acually will do and run the days work in Navigation. Here is the QMOW duties.
This go along with my thinking, Many can do the celo. but the Piloting must be left to the best.COMNAVSURFORINST/COMNAVAIRFORINST 3530. 4B 28 Jan 08
expected should be known and reported if reached. The Navigator must be advised if difficulty is experienced in obtaining a sounding. During restricted water transits the fathometer paper trace (if installed) will be activated and recording, annotated with the time of each mark.
(f) Quartermaster of the Watch (QMOW) The QMOW is the direct representative of the Navigator and provides a continuous navigational watch on the bridge. He/She will assist the Navigator and OOD in navigating the ship and will immediately inform the Navigator, OOD, Assistant Navigator, and Senior Quartermaster/Operations Specialist when discrepancies arise. The QMOW has numerous duties, including the keeping of various records, logs, and weather observations and obtaining fix information. The OOD must recognize this and if fix taking encumbers the QMOW from performing all other duties, the Senior Quartermaster/Operations Specialist, Assistant Navigator, and/or Navigator will be requested to provide additional assistance to the QMOW. This instruction cannot possibly cover all situations that may arise. However, he/she is charged with the following minimum responsibilities:
1. Assist the OOD, Navigator, and Assistant Navigator in plotting the ship’s position. Maintain a DR and Estimated Position plot. Immediately notify the Navigator of any discrepancies noted during the watch.
2. Maintain the Ship’s Deck Log, Magnetic Compass Record, and weather observation sheet.
3. Compare CIC/CDC/TOP derived positions and
ship’s relation to track and Position of Intended Movement (PIM)
with the bridge position and determine if differences exist.
(Not applicable to ECDIS-N certified ships.)
4. Compute and plot set and drift. (Not applicable to ECDIS-N certified ships.)
5. Calculate when an aid to navigation or RADAR landfall should be sighted and report whether or not it is detected as specified in the CO’s Standing Orders.
6. Note when a change in weather or the visibility decreases to less than the distance specified in the CO’s Standing Orders. Make appropriate log entries as required.

7. Determine the master/auxiliary gyrocompass errors daily and before entering restricted waters, recording any errors in the Bearing Book, Magnetic Compass Record Book, and Deck Log.
8. Ensure compass comparisons between the bridge gyrocompass/Inertial Navigation System (INS) repeaters and magnetic compass are made every time a new course is set and at least every 30 minutes, recording comparison data in the Magnetic Compass Record Book.
9. Note any malfunctions to all electronic navigation systems including speed and heading inputs. Inform the Navigator and OOD of any change in the status of such equipment and log in the Ship’s Deck Log the time and nature of such.
10. Obtain soundings using the fathometer at each fix, or as directed by the CO EMCON conditions permitting.
11. Calculate sunrise/sunset/moonrise/moonset and determine gyro error as directed by the Navigator.
12. Record 0800, 1200, and 2000 positions in the Ship’s Deck Log. If required by the Ca, prepare the ship’s 0800, 1200, and 2000 Ship’s Position Reports for submission to the Navigator. Electronic reports via email are authorized.
13. Prepare notes for CO’s Night Orders notebook as directed by the Navigator.
14. Before special evolutions, ensure UTC(USNO) time checks are conducted on the 1MC and logged in the Ship’s Deck Log.
15. Monitor the Helmsman/Lee Helmsman for compliance with ordered course and speed.
16. Conduct a watch turnover using a checklist such as that detailed in Appendix C.
