According to the Navigation Rules, if the compass bearing to an approaching vessel remains constant and the range is decreasing, what conclusion must be drawn?
- A. The vessels are in a crossing situation and the stand-on vessel must maintain course and speed
- ✓ Risk of collision existsCorrect
- C. The approaching vessel is the give-way vessel and must take action
- D. The vessels will pass safely without action because the bearing is steady
Why B is correct
Bowditch Ch. 7 §704 states that if the compass bearing to an approaching vessel remains constant and the range is decreasing (CBDR), risk of collision exists. A steady bearing alone does not identify which vessel is give-way, nor does it guarantee a safe pass.
