Official USCG Answer & Rule Citation
Correct Answer: Option A — 33'-00"
Mean draft increase is calculated by dividing added weight by Tons Per Inch (TPI) immersion. Adding 1200 tons divided by a TPI of 178 yields a 6.74-inch draft increase. Converting this to feet and inches results in an exact final mean draft of 33 feet, 0 inches.
