Question 548 Rules of the Road

The correct answer is D) restricted in her ability to maneuver. The International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules define a "vessel restricted in her ability to maneuver" as a vessel that, from the nature of her work, is restricted in her ability to maneuver as required by the rules and is therefore unable to keep out of the way of another vessel. A vessel transferring cargo while underway falls under this classification, as the transfer operation restricts the vessel's ability to maneuver freely. The other answer choices do not accurately describe the status of a vessel transferring cargo, as they refer to different navigational situations.
