Safety & Environmental Protection (Deck) USCG Question #3094 (Set 87)

Your vessel's drafts are: FWD 14'-11", AFT 16'-01"; and the KG is 23.2 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 C — 9,272 foot-tons

Mean draft is 15'-06". Identify the displacement from the reference tables. Using the stability curves for a KG of 23.2 feet, determine the GZ at 15 degrees. The product of displacement and GZ results in 9,272 foot-tons, which is the correct righting moment for this configuration.
