Safety & Environmental Protection (Deck) USCG Question #3285 (Set 93)

Your vessel's draft is 24'-06" forward and aft. The MT1 of your vessel is 1000 ft-tons. How many tons of cargo must be loaded in number 4 hold, which is 100 feet abaft the tipping center, if she is to have a 2 foot drag?

Official USCG Answer & Rule Citation

Correct Answer: Option B — 240 tons

The change in trim is calculated using the formula: Trim Change = (Weight × Distance from Tipping Center) / MT1. With a required 24-inch (2-foot) trim change and an MT1 of 1000 ft-tons, the weight is calculated as (24 inches × 1000) / 100 feet, resulting in 240 tons.
