Question 225 Deck General

The correct answer is D) course per magnetic steering compass. When relieving the helm, the new helmsman should know the course per the magnetic steering compass. This is because the magnetic compass is the primary means of steering the vessel, and the helmsman needs to be aware of the current course to maintain the desired direction of travel. Knowing the maximum rudder angle, variation, or gyro error (other answer choices) is not as critical for the immediate task of assuming the watch and continuing the vessel's course.
