Question 2166 Deck Safety
70% to passThe righting moment can be determined by multiplying the displacement by the _______________.
A
vertical center of gravity (KG)
B
righting arm (GZ)
C
longitudinal center of gravity (LCG)
D
center of gravity (CG)
AI Explanation
The correct answer is B) righting arm (GZ). The righting moment is determined by multiplying the vessel's displacement by the righting arm (GZ). The righting arm is the horizontal distance between the center of gravity (CG) and the center of buoyancy (CB) when the vessel is heeled. This distance, represented by GZ, creates a moment that acts to restore the vessel to an upright position. The other options (A, C, and D) do not directly determine the righting moment, which is the key factor in the vessel's stability.
