70% to pass

"An electronic or electric device that indicates the rate of turn of a vessel," defines a/an _______________.

A swing meter
B odometer
C magnetic compass
D gyro-compass
AI Explanation

The correct answer is A) swing meter. A swing meter is an electronic or electric device that indicates the rate of turn of a vessel. This is defined in the regulations for the US Coast Guard Captain's License Examinations. The swing meter provides crucial information to the vessel operator about the rate at which the ship is turning, which is important for navigation and collision avoidance. The other answer choices are incorrect because an odometer measures distance traveled, a magnetic compass indicates the direction the vessel is pointing, and a gyro-compass determines the true north heading of the vessel, rather than the rate of turn.
