Question 825 Rules of the Road

The correct answer is D) None of these day signals are correct. When operating a sailing vessel under power, the appropriate day signal to exhibit is not one of the options shown in the illustration. Instead, the vessel should display the shape of a black diamond according to the International and Inland Navigation Rules. This indicates that the vessel is no longer under sail alone and is using mechanical propulsion, which changes its maneuvering characteristics. The options provided in the illustration do not accurately represent the correct day signal required in this scenario.
