The DEEP DRILLER, loaded as shown in the Sample Load Form #4 (Drilling), discharges a non-liquid load of 275.8 long tons from a position 130 feet above the keel, 40 feet forward of amidships, and 30 feet to port of the centerline. What is the new KGL?

Correct Answer: Option C — 54.32 feet

Subtracting the discharged weight's vertical moments from the initial totals and dividing by the new displacement determines the revised vertical center of gravity. Under 46 CFR intact stability rules, the new KGL evaluates to 54.32 feet after removing the 275.8 long ton load from 130 feet high.
