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 D — The fishing vessel is directed not to impede the passage of the sailing vessel.

Rule 9(b) explicitly states that a vessel engaged in fishing shall not impede the passage of a vessel which can safely navigate only within a narrow channel. Because the sailing vessel is restricted to the channel, the fishing vessel is the one required to keep clear and not impede.
