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 improvement in KGL?

Correct Answer: Option C — 1.15 feet

Discharging 275.8 long tons from 130 feet above the keel removes a high vertical moment, lowering the vessel's vertical center of gravity. Dividing the net change in vertical moments by the new total displacement results in an improvement (reduction) in KGL of 1.15 feet, complying with 46 CFR stability standards.
