The DEEP DRILLER, at 60.0 feet draft in sea water, discharges 275.8 long tons. What is the new draft?

Correct Answer: Option B — 58 feet

Using tons-per-inch or parallel sinkage calculations, discharging 275.8 long tons reduces the displacement, resulting in a draft change that brings the vessel from 60.0 feet up to the exact calculated hydrostatic draft of 58 feet.
