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 GMT?

Correct Answer: Option D — 9.24 feet

Discharging weight from a high, forward, and port position raises the center of gravity and alters transverse and longitudinal moments. Using the stability booklet and Sample Load Form #4 data for the DEEP DRILLER results in a recalculated transverse metacentric height (GMT) of 9.24 feet.
