Which vessel status indicates the ship cannot maneuver?

• A. Not Under Command
• B. Restricted Ability to Maneuver
• C. Constrained by Drift
• D. Sailing

Answer: (A)

Not Under Command means the vessel cannot maneuver as required by the collision regulations due to an exceptional circumstance, such as a breakdown of steering gear or propulsion. Because it cannot alter its course or speed to avoid danger, other vessels must treat it with extreme caution and keep well clear, as if it were completely unable to maneuver. A vessel described as restricted in its ability to maneuver still has some maneuvering capability, even if limited, so it isn’t conveying an absolute loss of control. A term like sailing indicates the vessel can still maneuver under its current means (sails) rather than being unable to move as needed. “Constrained by drift” isn’t a standard designation for maneuvering status. Thus the description that communicates an outright inability to maneuver is Not Under Command.
