Question 102 Rules of the Road

The correct answer is D) A vessel is on your starboard quarter, range decreasing, bearing is constant. This situation indicates a risk of collision because the bearing of the other vessel is constant, meaning it is on a collision course. When the range is decreasing and the bearing is constant, it means the two vessels are converging, and there is a high probability of a collision occurring. The other options are incorrect because: A) The bearing is changing rapidly, indicating the vessels are not on a collision course. B) The range is increasing, indicating the vessels are moving apart, not converging. C) The range is increasing, and the bearing is changing slightly, indicating the vessels are not on a collision course.
