Question 4118 Deck General

When piloting a vessel, how are visual references used to establish a constant rate of turn?

A Keep the fixed object's relative bearing opening, for a constant rate of turn.
B Begin the turn when the fixed object is on the beam.
C Fixed objects that stay on the same relative bearing when the ship is turning indicate a constant rate of turn.
D Visual references cannot be used to maintain a constant rate of turn.
AI Explanation

The correct answer is C) Fixed objects that stay on the same relative bearing when the ship is turning indicate a constant rate of turn. When a vessel is turning, the relative bearing of a fixed object on the horizon will change. If the relative bearing of the fixed object remains constant during the turn, it indicates that the vessel is maintaining a constant rate of turn. This is because a constant rate of turn will cause the fixed object's relative bearing to change at a constant rate. By monitoring fixed objects and ensuring their relative bearings remain steady, the pilot can visually confirm they are holding a consistent turning rate. The other answer choices are incorrect because A) opening relative bearings indicate an increasing rate of turn, B) the beam position is not necessary to maintain a constant rate, and D) visual references can in fact be used to monitor and maintain a constant rate of turn.
