The DEEP DRILLER at a draft of 58.0 feet loads 68.94 long tons of ballast. What is the new draft?
Official USCG Answer & Rule Citation
Correct Answer: Option C — 58.5 feet
Loading ballast increases total displacement. Entering the vessel's stability manual curves for a 58.0-foot draft and adding 68.94 long tons results in an increased parallel sinkage, yielding a new draft of 58.5 feet.
