Question 275Safety & Environmental - 1st Asst/Chief

The correct answer is A) Vertical. Yawing is the angular motion of a vessel about its vertical axis. This means the vessel is rotating around an imaginary axis that runs from the top to the bottom of the vessel, perpendicular to the waterline. The other options are incorrect because: B) Longitudinal refers to motion along the length of the vessel, C) Centerline refers to the imaginary line running along the center of the vessel, and D) Transverse refers to motion across the width of the vessel. Yawing specifically describes the rotational motion about the vertical axis.
