Question 1748Deck Safety70% to pass
A concentration of weight has been shifted inboard to the center line of the vessel. Generally speaking, what effect will this have on the vessel?
AI Explanation
The correct answer is B) the vessel's rolling period will decrease.
When the weight is shifted inboard towards the center line of the vessel, the metacentric height (GM) of the vessel increases. This increase in GM results in a shorter rolling period, as the vessel will have a higher restoring force when it starts to roll. A higher GM means the vessel is more stable and will have a quicker response to rolling motions, leading to a decreased rolling period.
The other options are incorrect because A) the rolling period would not remain the same, C) the rolling period would not increase, and D) the rolling would not be rapid, but rather quicker due to the increased stability.
