Question 557 Rules of the Road

The correct answer is B) A 16-meter sailing vessel. According to the International Regulations for Preventing Collisions at Sea (COLREGS), a sailing vessel of less than 20 meters in length may combine her sidelights and stern light in one lantern carried on the fore and aft centerline of the vessel. This regulation applies to both international and inland waters. The other options are incorrect because: A) A 28-meter sailing vessel is too large to combine the lights, C) Non-self-propelled vessels have different lighting requirements, and D) A 25-meter power-driven vessel is also too large to combine the lights.
