Question 1732Deck Safety70% to pass
The horizontal port or starboard movement of a vessel is called _______________.
AI Explanation
The correct answer is C) sway.
Sway refers to the horizontal, side-to-side motion of a vessel. This is one of the six degrees of freedom that a vessel experiences, the others being surge (forward/backward motion), heave (up/down motion), roll (rotation around the longitudinal axis), pitch (rotation around the transverse axis), and yaw (rotation around the vertical axis).
The other answer choices are incorrect because they refer to different types of vessel motion - surge for forward/backward motion, heave for up/down motion, and yaw for rotation around the vertical axis.
