Question 523Rules of the Road90% to pass
BOTH INTERNATIONAL & INLAND The stern light shall be positioned such that it will show from dead astern to how many degrees on each side of the stern of the vessel?
AI Explanation
The correct answer is B) 67.5°.
According to the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules, the stern light must show from dead astern to 67.5° on each side of the vessel. This ensures that the stern light is visible from a wide arc around the stern, allowing other vessels to determine the orientation of the ship.
The other options are incorrect because A) 22.5° is too narrow, C) 112.5° is too wide, and D) 135.0° is also too wide for the required visibility of the stern light.
