Question 849 Rules of the Road

The correct answer is B) a broken down vessel. The shapes shown in illustration D007RR are the shapes required to be displayed by a vessel that is not under command, which is the international and inland navigation term for a vessel that is unable to maneuver as required by the rules due to some exceptional circumstance, such as being disabled or broken down. The other answer choices are incorrect because minesweepers, vessels transferring dangerous cargo, and fishing vessels have different shape requirements that are not depicted in the given illustration.
