A weight of 350 tons is loaded on your vessel 85 feet forward of the tipping center. The vessel's MT1 is 1150 foot-tons. What is the total change of trim?
Official USCG Answer & Rule Citation
Correct Answer: Option C — 25.87 inches
Total change of trim is calculated using the moment divided by the moment to change trim 1 inch (MT1). Multiplying 350 tons by 85 feet gives a trim moment of 29,750 foot-tons. Dividing 29,750 by 1,150 foot-tons yields a total change of trim of 25.87 inches.
