USCG Exam PracticeThree-bearing fix and cocked-hat triangle
The cocked-hat triangle from a three-bearing fix lies adjacent to a charted shoal. Where should the navigator plot the vessel's assumed position?
- A. At the geometric centre of the triangle
- ✓ At the corner of the triangle nearest the hazardCorrect
- C. At the corner of the triangle farthest from the hazard
- D. At the midpoint of the side of the triangle parallel to the shoal
Why B is correct
Bowditch Ch. 7 §705 states that where the cocked-hat triangle lies near a hazard, the corner nearest the danger is assumed for safety. This conservative practice ensures the navigator does not underestimate proximity to the hazard.
