USCG Exam PracticeVisual piloting — three-bearing fixes, danger bearings
A line of position (LOP) derived from a single bearing observation tells you MOST precisely that your vessel is:
- A. At the exact point where the bearing line crosses the chart
- ✓ Somewhere along the line drawn through the observed object at the measured bearingCorrect
- C. At the intersection of two simultaneously observed bearings
- D. On a DR track advanced from the last known fix
Why B is correct
A single LOP establishes only that the vessel lies somewhere along that line at the moment of observation. A fix requires the intersection of two or more LOPs taken simultaneously. Bowditch Ch. 7 §701.
