Which of the following defines "Rolling Period"?

Correct Answer: Option B — the time it takes the vessel to make a complete roll such as from port to starboard and back to port

The rolling period is defined as the time interval required for a vessel to complete one full cycle of oscillation. This includes the movement from the maximum angle on one side (e.g., port), through the upright position to the maximum angle on the opposite side (starboard), and back to the starting point.
