USCG Exam PracticeDanger bearings and danger circles
When constructing a danger bearing on a chart, the reference line is drawn from the charted object to:
- A. The vessel's DR position at the time of the first bearing observation
- B. The centre of the off-lying hazard as charted
- C. The intersection of the two most recent lines of position
- ✓ The nearest edge of the off-lying hazard or a safe-distance danger circle around itCorrect
Why D is correct
Per Bowditch Ch. 7 §706, the line is drawn from the charted object tangent to the edge of the hazard or to a danger circle scribed at a safe distance around it. Drawing to the centre would place the line through the hazard itself.
