Question 744 Rules of the Road

The correct answer is C) 11.9 meters. According to the U.S. Coast Guard regulations, a power-driven vessel of less than 12 meters (39.4 feet) in length may show an all-round white light and sidelights instead of the standard configuration of a masthead light, sidelights, and a stern light. This regulation applies to both international and inland waterways. The other options are incorrect because 6.9 meters is too short, 9.9 meters is still under the 12-meter limit, and 19.9 meters exceeds the 12-meter threshold for this alternative lighting configuration.
