Question 827Rules of the Road90% to pass

BOTH INTERNATIONAL & INLAND Your 18-meter vessel is propelled by sail and power. What action is required when the engine is stopped?

AI Explanation
The correct answer is C) Remove the black cone shape from forward. When a sailing vessel with an auxiliary engine is under sail alone (engine stopped), the vessel must remove the black cone shape that is required to be displayed when the engine is running. This is specified in the International and Inland Navigation Rules (COLREGS), which govern the display of navigation lights and shapes for vessels. Removing the black cone shape indicates to other vessels that the vessel is now operating under sail alone, rather than power. The other options are incorrect because: A) displaying a black diamond shape is not required when the engine is stopped, B) removing the black balls is not necessary, and D) displaying a black cylindrical shape is also not the correct action in this situation.
