The DEEP DRILLER is loaded as shown in the Sample Load Form #2 (Ballasting to Survival). What is the new height of the longitudinal metacenter if all the bulk materials are discharged?

Correct Answer: Option C — 62.35 feet

Longitudinal metacenter height (KMl) is a function of waterplane area and draft. After discharging bulk materials, the resulting change in mean draft shifts the waterline geometry, yielding a revised longitudinal metacenter height of 62.35 feet per hydrostatic particulars.
