Question 2089 Deck Safety

The correct answer is B) virtual height of the center of gravity. Increasing the number of slack liquid tanks has the effect of raising the virtual height of the center of gravity (VCG) of the vessel. This is because the free surface effect of the slack liquid causes the actual center of gravity to rise, increasing the VCG. The metacentric height (GM) is not directly affected, as it depends on the relationship between the VCG and the vessel's geometry. The uncorrected KG and the maximum allowed KG are also not directly impacted by the number of slack liquid tanks.
