Which of the following defines "Rolling Period"?
AI Explanation
The correct answer is B) the time it takes the vessel to make a complete roll such as from port to starboard and back to port.
The term "rolling period" refers to the time it takes for a vessel to complete one full cycle of rolling from port to starboard and back to port. This is the standard definition of rolling period, as it captures the full oscillation of the vessel from one side to the other and back to the starting point.
The other options are incorrect because they do not accurately describe the complete cycle of the rolling motion. Option A describes only half the roll, from level to starboard and back. Option C omits the return to the original port side, and option D only describes the roll from port to level, not the full cycle.
