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

Correct Answer: Option B — 56.55 feet

Discharging weight from a floating vessel decreases draft proportionally to the TPI (Tons Per Inch) or metric equivalent from hydrostatic particulars. Utilizing the DEEP DRILLER stability manual curves for seawater displacement at 58.0 feet draft results in a new draft of 56.55 feet.
