Question 116 Rules of the Road

The correct answer is B) in general, keep well clear of all vessels. The International and Inland Navigation Rules (COLREGS) treat seaplanes as vessels when they are on the water. Rule 18 states that a seaplane on the water shall, in general, keep well clear of all vessels and avoid impeding their navigation. This is because seaplanes have limited maneuverability compared to traditional vessels, and they need to be cautious when operating in the vicinity of other traffic. The other answer choices are incorrect. Option A is incorrect because there is no specific requirement for seaplanes to proceed at a slower speed than surrounding vessels. Option C is incorrect because seaplanes are not required to show the lights for a vessel not under command. Option D is incorrect because the rules do consider seaplanes as vessels when they are on the water.
