USCG Exam PracticeDanger bearings and danger circles
33 CFR §83.07(d)(ii) states that risk of collision may sometimes exist even when an appreciable bearing change is evident. In which of the following situations does this provision specifically apply?
- A. When overtaking a vessel in a narrow channel at night
- ✓ When approaching a very large vessel or a tow, or when approaching a vessel at close rangeCorrect
- C. When two power-driven vessels are meeting head-on in open water
- D. When a vessel is anchored and swinging on her cable
Why B is correct
33 CFR §83.07(d)(ii) specifically identifies three situations where risk may exist despite an appreciable bearing change: approaching a very large vessel, approaching a tow, or approaching any vessel at close range. The geometry of large vessels and tows means that passing clear of the bow does not guarantee clearing the entire length of the vessel or tow.
