USCG Exam PracticeRule 9 — Narrow Channels
In a narrow channel, a power-driven vessel intends to overtake another power-driven vessel. Under the Inland Navigation Rules, what must the overtaking vessel do before passing?
- A. Sound the danger signal and wait for a response before maneuvering
- ✓ Sound the appropriate signal under Rule 34(c) and take steps to permit safe passingCorrect
- C. Contact the vessel being overtaken by radiotelephone only, with no whistle signal required
- D. Proceed with the overtaking maneuver without signaling, as Rule 13 governs overtaking exclusively
Why B is correct
Inland Rule 9(e)(i) requires the overtaking power-driven vessel to indicate her intention by sounding the appropriate signal prescribed in Rule 34(c) and take steps to permit safe passing. Rule 9(e)(ii) further clarifies this does not relieve the overtaking vessel of her obligations under Rule 13.
