Question 2024 Deck Safety

The correct answer is B) Metacentric height will increase. Removing on-deck containers will result in a decrease in the vessel's overall weight, which will cause the metacentric height (GM) to increase. The metacentric height is a measure of a vessel's stability and is directly related to the position of the center of gravity (KG) and the center of buoyancy (KB). When the weight of the on-deck containers is removed, the KG and KB values will change, leading to an increase in the GM and, consequently, an improvement in the vessel's stability. The other options are incorrect because: A) Reserve buoyancy will decrease is not the primary effect of removing on-deck containers. C) KG will increase is incorrect because the removal of on-deck containers will typically lower the overall center of gravity. D) KB will increase is incorrect because the removal of on-deck containers will not directly affect the center of buoyancy.
