Question 651 Rules of the Road

The correct answer is B) from the nature of her work is unable to maneuver as required by the rules. This is correct because the definition of a "vessel restricted in her ability to maneuver" in both the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules refers to a vessel that, from the nature of her work, is unable to maneuver as required by the rules. This includes vessels engaged in activities such as dredging, surveying, cable-laying, or underwater operations. The other answer choices are incorrect because they do not accurately describe the definition of a "vessel restricted in her ability to maneuver" as stated in the rules.
