The DEEP DRILLER is loaded as shown in the Sample Load Form #1 (Transit). What are the new vertical moments if the entire contents of Salt Water Ballast Tanks 1P and 1S are discharged?

Correct Answer: Option B — 794,346 ft-tons

Vertical moments are recalculated by subtracting the vertical moments of the discharged ballast tanks from the initial total vertical moments, applying standard hydrostatic weight-moment reduction formulas outlined in marine stability and 46 CFR guidelines.
