The COASTAL DRILLER is loaded as shown in the Sample Load Form Number 1 (Rig Move). If the contents of the No.1 drill water tank are discharged, what would be the new LCG?

Correct Answer: Option D — 120.42 feet AF0

Removing weight from a specific location alters the vessel's LCG by taking final moments divided by final displacement. Discharging the contents of No.1 drill water tank shifts the longitudinal center of gravity to 120.42 feet aft of frame zero (AF0).
