Deck General USCG Question #4410 (Set 141)

While loaded as shown in the DEEP DRILLER Sample Load Form #4 (Drilling), all of the liquid mud is dumped. What is the new longitudinal metacentric height?

Official USCG Answer & Rule Citation

Correct Answer: Option C — 7.33 feet

Dumping all liquid mud removes substantial fluid weight and eliminates associated free surface effects, significantly raising the longitudinal metacenter relative to the lowered center of gravity. This weight reduction results in a new longitudinal metacentric height of 7.33 feet, ensuring safe trim parameters.
