BOTH INTERNATIONAL & INLAND When underway in a channel, which action should you take, if it is safe and practicable?
Official USCG Answer & Rule Citation
Correct Answer: Option D — keep to the side of the channel which lies to your starboard
Rule 9(a) mandates that a vessel proceeding along a narrow channel or fairway shall, when it is safe and practicable, keep to the side of the channel which lies to her starboard. This standardizes navigation and reduces the likelihood of head-on encounters within restricted waters.
