Question 2094 Deck Safety

The correct answer is A) decreases. As the displacement of a vessel increases, the detrimental effect of free surface decreases. This is because as the vessel's displacement increases, the relative effect of the free surface on the vessel's stability becomes less significant. With a larger displacement, the vessel's inherent stability characteristics become more dominant, and the impact of free surface is diminished. The other options are incorrect because: B) the effect of free surface is not dependent on the vessel's form, C) the effect of free surface actually decreases as displacement increases, and D) the effect of free surface does not remain the same as displacement changes.
