Your vessel's drafts are: FWD 19'-03", AFT 21'-03". The LCG of the forepeak is 200 feet forward of amidships. How many tons of ballast must be pumped into the forepeak in order to have a drag of 18 inches? (Use the reference material in Section 1, the blue pages, of the Stability Data Reference Book)

Question

Accepted Answer

Option B: 31 tons. Determining the initial trim from the 19'-03" forward and 21'-03" aft drafts and applying standard trim correction formulas using the stability tables shows that 31 tons of ballast in the forepeak achieves an 18-inch drag.
