When displacement increases, the free surface corrections for slack tanks _______________.
AI Explanation
The correct answer is C) decrease.
When a vessel's displacement increases, the free surface corrections for slack tanks will decrease. This is because as the vessel's displacement increases, the relative size of the free surface area in the slack tanks becomes smaller, reducing the impact of the free surface effect on the vessel's stability. The free surface corrections are directly related to the free surface area, so as the displacement increases, the free surface corrections will decrease accordingly.
The other options are incorrect because: A) the free surface corrections are not directly proportional to displacement, but rather decrease as displacement increases; B) the free surface corrections decrease, not increase, with increasing displacement; and D) the free surface corrections do not remain unchanged, but rather decrease as displacement increases.
