The DEEP DRILLER at a draft of 60.0 feet discharges 68.94 long tons of ballast. What is the new draft?
Official USCG Answer & Rule Citation
Correct Answer: Option C — 59.5 feet
Discharging weight decreases displacement and draft. Using the vessel's tons per inch or foot immersion curves from the stability booklet, removing 68.94 long tons at a 60-foot draft decreases the draft to 59.5 feet.
