Which option below correctly describes a vessel not under command?

• A. A vessel that is anchored
• B. A vessel which, through some exceptional circumstance, is unable to maneuver as required by the rules
• C. A vessel that is towing another
• D. A vessel that is fishing

Answer: (B)

Not under command describes a vessel that, because of an exceptional circumstance, cannot maneuver as required by the Rules and therefore cannot keep out of the way of other vessels. This exact condition—an unforeseen loss of ability to steer, power, or otherwise maneuver to comply with the Rules—is what the term covers. Engine or steering failure are classic examples, which is why the option stating this situation is the correct description. A vessel that is anchored isn’t defined by an inability to maneuver under the Rules; it’s stationary by choice and can become maneuverable again by getting underway or lifting anchor. A vessel that is towing has operational constraints but remains able to maneuver within the Rules, not inherently not under command. A fishing vessel is engaged in specific activity with its own navigation considerations, but that alone doesn’t mean it cannot maneuver as required by the Rules. So the description that aligns with the formal meaning of Not under command is the one that speaks to an exceptional circumstance rendering the vessel unable to maneuver as required.
