The COASTAL DRILLER is loaded as shown in the Sample Load Form Number 1 (Rig Move). If the contents of the No.7 drill water tank are discharged, what would be the new TCG?

Correct Answer: Option C — 0.15 foot

Applying transverse center of gravity moments from the COASTAL DRILLER stability booklet demonstrates that discharging No. 7 drill water shifts the vessel's center of gravity laterally by 0.15 foot, altering the overall transverse stability characteristics.
