Safety & Environmental Protection (Deck) USCG Question #3240 (Set 91)

Addition of weight above the center of gravity of a vessel will ALWAYS __________.

Official USCG Answer & Rule Citation

Correct Answer: Option B — reduce initial stability

Adding weight above the center of gravity raises the vessel's KG. Because GM equals KM minus KG, an increase in KG results in a smaller GM. A reduced GM decreases the vessel's righting arm at small angles, thereby reducing initial stability, which is critical for safe vessel operations under 46 CFR.
