Question 277Safety & Environmental - 1st Asst/Chief
70% to passThe horizontal port or starboard movement of a vessel is called _______________.
Aheave
Bsway
Csurge
Dyaw
AI Explanation
The correct answer is B) sway. Sway refers to the horizontal port or starboard movement of a vessel. This is one of the six degrees of freedom that describe the motion of a vessel, the others being surge (forward and backward movement), heave (up and down movement), 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 heave refers to the up and down movement, surge refers to the forward and backward movement, and yaw refers to the rotation around the vertical axis, rather than the horizontal port or starboard movement.
