Question 1746 Deck Safety

The correct answer is A) pitching period. The pitching period is the time required for a vessel to incline from a bow-down position to a stern-down position and then return to the original bow-down position. This back-and-forth motion is known as pitching, and the time it takes to complete one full cycle is called the pitching period. The other options are incorrect because: B) rolling period refers to the time required for a vessel to roll from one side to the other and back again. C) inclining moment is the force that causes a vessel to incline or list to one side. D) amplitude moment is not a standard term used in naval architecture or ship stability.
