Angular motion about the vertical axis of a vessel is called _______________.

AI Explanation
The correct answer is C) yaw. Yaw is the angular motion of a vessel about its vertical axis, which causes the vessel to turn left or right. This is one of the three primary motions of a vessel, along with roll (angular motion about the longitudinal axis) and pitch (angular motion about the transverse axis). The other answer choices are incorrect because: A) Sway refers to the lateral, side-to-side motion of a vessel. B) Roll is the angular motion about the longitudinal axis. D) Surge is the forward and backward motion of a vessel along its longitudinal axis.
