Safety & Environmental Protection (Deck) USCG Question #2279 (Set 70)

The SS AMERICAN MARINER has drafts of: FWD 26'-04", AFT 28'-08". Use the white pages of the Stability Data Reference Book to determine the drafts if you ballast the forepeak with 101 tons of seawater.

Official USCG Answer & Rule Citation

Correct Answer: Option A — FWD 27'-01.2", AFT 28'-02.5"

Ballasting 101 tons of seawater into the forepeak alters longitudinal stability. Reference book hydrostatic data applied to initial drafts of FWD 26'-04" and AFT 28'-08" results in updated draft measurements of FWD 27'-01.2" and AFT 28'-02.5".
