USCG Exam PracticeDanger bearings and danger circles
When monitoring an approaching vessel by compass bearing, risk of collision shall be deemed to exist if which of the following conditions is observed?
- A. The bearing draws steadily aft
- ✓ The bearing does not appreciably changeCorrect
- C. The bearing draws steadily forward
- D. The range increases while bearing remains steady
Why B is correct
33 CFR §83.07(d)(i) states that risk of collision shall be deemed to exist if the compass bearing of an approaching vessel does not appreciably change. A bearing drawing forward or aft indicates the vessels will pass clear, and an increasing range removes the collision threat.
