Question 797 Rules of the Road

The correct answer is A) has a tow that exceeds 200 meters in length. The shape shown in illustration D010RR represents the day signal for a vessel that is towing another vessel or object where the length of the tow, measured from the stern of the towing vessel to the after end of the tow, exceeds 200 meters. This signal is required by both the International and Inland Rules of the Road to indicate the extended length of the tow. The other answer choices are incorrect because B) a vessel at anchor would display different day shapes, C) a vessel carrying dangerous cargo would display a different set of signals, and D) a vessel not under command would display a different shape.
