Question 833 Rules of the Road

The correct answer is D) is fishing. The shape in illustration D034RR depicts the navigational shape for a vessel engaged in fishing. According to both the International and Inland Navigation Rules, vessels engaged in fishing must display this diamond shape to indicate their status and activity to other vessels in the vicinity. The other answer choices are incorrect because they do not match the navigational shape shown in the illustration. A vessel with a tow exceeding 200 meters, a vessel not under command, or a vessel engaged in surveying or underwater work would display different navigational shapes to communicate their status to other vessels.
