USCG Exam Practice · Danger bearings and danger circles

33 CFR §83.07(d)(ii) notes that risk of collision may sometimes exist even when an appreciable bearing change is evident. In which of the following situations does this caution specifically apply?

  1. AWhen approaching a vessel displaying restricted-in-ability-to-maneuver signals
  2. BWhen approaching a very large vessel or a tow, or when approaching a vessel at close range✓ correct
  3. CWhen the other vessel is on a reciprocal course at high speed
  4. DWhen operating in a traffic separation scheme

Why B is correct

33 CFR §83.07(d)(ii) specifically identifies approaching a very large vessel, a tow, or a vessel at close range as situations where risk of collision may exist despite an appreciable bearing change. The physical size of the vessel or tow means that even with bearing change, part of the other vessel may still be on a collision course.
