Question 2519Deck Safety70% to pass
When the wave period and the apparent rolling period are the same _______________.
AI Explanation
The correct answer is A) synchronous rolling occurs.
When the wave period and the apparent rolling period of a ship are the same, it results in synchronous rolling. This means the ship's rolling motion is in sync with the wave motion, causing the roll amplitude to increase significantly, leading to potentially dangerous situations. The other answer choices are incorrect because they do not accurately describe the effect of matching wave and roll periods. Dampening of roll amplitude, decrease in roll period, or increase in roll period are not the primary consequences of this phenomenon.
