After refueling your vessel you notice that the GM of the vessel is less than the required 0.15 meters. What do you do?

Correct Answer: Option B — Transfer the fuel to lower the ship's KG and minimize the free surface effect.

When GM falls below the 0.15-meter regulatory threshold, the vessel lacks sufficient stability. Transferring fuel to lower tanks lowers the center of gravity (KG) and reduces the free surface effect, which directly increases the metacentric height, ensuring the vessel complies with international stability criteria for safe operation.
