Question 2057 Deck Safety

The correct answer is D) vertical moments. When the height of the vessel's center of gravity increases due to loading, the vertical moments acting on the vessel also increase. This is because the vertical moments are directly proportional to the height of the center of gravity. An increase in the center of gravity height leads to an increase in the vertical moments, which can impact the vessel's stability and seaworthiness. The other answer choices are incorrect because: A) Righting moment may not always increase, as it depends on the vessel's geometry and loading conditions. B) Righting arm may not necessarily increase, as it is calculated based on the vessel's stability characteristics. C) Metacentric height may decrease or increase depending on the specific loading conditions.
