Safety & Environmental Protection (Deck) USCG Question #3091 (Set 87)

Your vessel's drafts are: FWD 17'-05", AFT 20'-01"; and the KG is 22.4 feet. What is the righting moment when the vessel is inclined to 15°? (Use the reference material in Section 1, the blue pages, of the Stability Data Reference Book)

Official USCG Answer & Rule Citation

Correct Answer: Option A — 10,656 foot-tons

Determine displacement from the mean draft of 18'-09". Using the stability curves for a KG of 22.4 feet, identify the GZ value at 15 degrees. Multiplying displacement by this GZ value results in a righting moment of 10,656 foot-tons, adhering to the vessel's specific hydrostatic characteristics.
