Question 3910Deck General70% to pass
When the period of beam seas equals the natural rolling period of a vessel, what will most likely occur?
AI Explanation
The correct answer is C) Excessive rolling.
When the period of beam seas (the time it takes for the wave crest to pass a fixed point) equals the natural rolling period of a vessel, the vessel will experience excessive rolling. This is due to the phenomenon of resonance, where the external force (the waves) matches the natural frequency of the vessel, causing the rolling motion to be amplified. This excessive rolling can lead to stability issues and potential capsize if not addressed.
The other options are incorrect because excessive yawing and pitching are not the primary concerns when the wave period matches the natural rolling period. There would also not be "no change" evident, as the vessel would clearly experience the excessive rolling.
