USCG Exam PracticeRule 9 — Narrow Channels
On the Great Lakes, a downbound power-driven vessel with a following current and an upbound power-driven vessel are meeting in a narrow channel. The upbound vessel disagrees with the proposed manner of passage. Under Inland Rule 9(a)(ii), what is the correct action for the upbound vessel?
- A. The upbound vessel may counter-propose an alternative passage and initiate her own maneuvering signals.
- B. The upbound vessel shall sound the danger signal and both vessels must stop and agree by radio before proceeding.
- ✓ The upbound vessel shall hold as necessary to permit safe passing as directed by the downbound vessel.Correct
- D. The upbound vessel assumes the right-of-way because the downbound vessel failed to obtain agreement before initiating signals.
Why C is correct
Inland Rule 9(a)(ii) assigns right-of-way to the downbound vessel with a following current on the Great Lakes and Western Rivers. The upbound vessel shall hold as necessary to permit safe passing; the Rule does not provide the upbound vessel authority to counter-propose or assume right-of-way. If in doubt, the vessel may use the doubt/danger signal under Rule 34(d).
