How is a "vessel not under command" described in navigation rules?

• A. Unable to keep out of the way of another vessel due to her work
• B. Unable to maneuver due to exceptional circumstances
• C. Created a special circumstance situation by acting contrary to the rules
• D. Moored, aground, or anchored in a fairway

Answer: (B)

A "vessel not under command" refers to a situation in navigation rules where a vessel is unable to maneuver as required due to exceptional circumstances. This could include situations such as mechanical failure, power loss, or other emergencies that impair the vessel's ability to navigate safely. Such vessels may not be able to take the necessary actions to yield the right of way or avoid collisions, which is a crucial concept in maritime navigation to ensure safety at sea. By following this definition, it is clear why identifying a vessel as "not under command" is important. It alerts other vessels that special care must be taken when in proximity to this vessel, as it cannot follow regular navigation rules as dictated by the maritime navigation regulations. This understanding helps maintain safety on the water and prevents accidents that could arise from assumptions about a vessel's ability to maneuver. The other options do not accurately capture the essence of what constitutes a "vessel not under command." For example, a vessel that simply cannot keep out of the way due to her work, or one that has created a circumstance by acting against the rules, may still have some degree of maneuverability. Additionally, a vessel that is moored, aground, or anchored does not fall under the definition of being "not
