As Chief Engineer or First Assistant Engineer you should be familiar with the six motions of a vessel. Which of these motions affects the governing "transverse" stability?

Correct Answer: Option A — Roll

Roll is the rotational motion of a vessel about its longitudinal axis. This motion directly impacts transverse stability, as it involves the oscillation of the center of gravity relative to the metacenter. Understanding roll is fundamental to maintaining the vessel's righting arm and overall stability during operations.
