The SS AMERICAN MARINER has the liquid load shown in table ST-0063 below. Use the white pages of The Stability Data Reference Book to determine the KG of the liquid load.

Correct Answer: Option D — 6.8 feet

Liquid load vertical centers are extracted directly from vessel tank capacity and sounding tables. Reference table ST-0063 lists specific volumes and corresponding vertical heights, yielding a total liquid load vertical center of gravity (KG) of 6.8 feet above the keel.
