Question 2021 Deck Safety

The correct answer is A) height of the center of gravity. Dividing the sum of the vertical moments by the total weight of the vessel yields the height of the vessel's center of gravity. This is a fundamental principle in naval architecture and stability calculations. The center of gravity is a critical factor in determining a vessel's stability and how it will respond to external forces, such as wind and waves. The other answer choices are incorrect because: B) inclining moments refer to the moments created during an inclining experiment to determine the vessel's stability characteristics; C) righting moments are the moments that act to restore a vessel to the upright position when it is heeled; and D) vertical moments are the individual moments acting on the vessel in the vertical plane.
