USCG Exam PracticeDanger bearings and danger circles
When a danger circle is used in constructing a danger bearing, the circle is scribed around the hazard at:
- A. The charted depth contour that equals the vessel's draft
- ✓ A safe distance from the hazard, and the danger bearing line is drawn tangent to that circleCorrect
- C. The radius equal to the distance from the reference object to the nearest edge of the hazard
- D. A fixed radius of 0.25 nautical miles regardless of the hazard size
Why B is correct
Bowditch Ch. 7 §706 states the danger circle is scribed at a safe distance around the hazard and the bearing line is drawn from the charted object tangent to that circle. The source does not specify a fixed radius; the mariner selects the safe clearance distance.
