BOTH INTERNATIONAL & INLAND A sailing vessel is proceeding along a narrow channel and can safely navigate ONLY inside the channel. The sailing vessel approaches a vessel engaged in fishing. Which statement is TRUE?

Correct Answer: Option B — The fishing vessel shall not impede the passage of the sailing vessel.

Rule 9(b) mandates that a vessel engaged in fishing shall not impede the passage of a vessel which can safely navigate only within a narrow channel. Since the sailing vessel is restricted to the channel, the fishing vessel must yield, regardless of its usual status as a stand-on vessel.
