BOTH INTERNATIONAL & INLAND A vessel engaged in fishing shall keep out of the way of which of the following vessels?

Correct Answer: Option B — restricted in her ability to maneuver

Rule 18 establishes a hierarchy of responsibility. A vessel engaged in fishing, while generally having right-of-way over power-driven vessels, must still keep out of the way of a vessel restricted in her ability to maneuver (RAM), as RAM vessels are higher in the hierarchy of maneuverability requirements.
