19. OOD Conning CO Officer Bearing Taker Chart Table Navigator Bridge Plotter Bearing Recorder CIC Radar Chart Operator Table Plotter Piloting Officer The Navigator’s Report “Based on an excellent fix at time :20, Navigation holds us 100 yards left of track. Nearest hazard to navigation is shoal water 500 yards off the port bow. Nearest aid to navigation is red buoy 8, off the stbd beam. Fathometer reads 45 feet beneath the keel, concurs with charted depth. Distance remaining this leg; 2,500 yards. Next time to turn with be at time :25 to new course 095 °T. Turn bearing is 272°T to Castle Rock. Navigation recommends coming right to new course 045º to regain track. Set and drift is 090ºT at 1 knot.” “CIC concurs/does not concur.” Bearing Taker

20. Navigator’s Reports • Based on an excellent [type of] fix at time :20 • Navigation holds us 100 yards left of track. • Nearest hazard to navigation is shoal water 500 yards off the port bow. • Nearest aid to navigation is red buoy 8, off the stbd beam. • Fathometer reads 45 feet beneath the sonar dome, concurs with charted depth. • Distance remaining this leg; 2,500 yards. • Next time to turn with be at time :25 to new course 095T. • Turn bearing is 272° to Castle Rock. • Navigation recommends coming right to new course 045º to regain track. • Set and drift is 090ºT at 1 knot.” • “CIC concurs.”

21. How do you shoot bearings? • On the beam first, then forward and aft. • Lines will cross in triangle. Where is the ship’s position?

22. Cardinal Rule • “No single source of information should be relied upon to the exclusion of others”

23. Fix intervals • Water depth constraints • Current • Bottom contour • Weather • Navigational hazards • Speed • Simply put, how quickly you can get into trouble!
