USCG Exam PracticeDanger bearings and danger circles
When constructing a danger bearing on a chart, the line is drawn from the charted object to:
- A. The vessel's DR position at the time of the observation
- ✓ The tangent of the hazard's edge, or to a danger circle scribed at a safe distance around the hazardCorrect
- C. The nearest aid to navigation seaward of the hazard
- D. The intersection of two simultaneous lines of position
Why B is correct
Bowditch Ch. 7 §706 states 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. The DR position and aids to navigation are not part of the danger bearing construction.
