The DEEP DRILLER, at 58.0 feet draft in sea water, discharges 200 long tons. What is the new displacement?

Correct Answer: Option B — 17,642 long tons

Discharging weight decreases total displacement by the exact mass removed. Subtracting 200 long tons from the initial displacement at the 58.0-foot operating draft results in a new displacement of exactly 17,642 long tons as verified by hydrostatic curves.
