366. Your vessel's drafts are: FWD 14'-04″, AFT 17'-08″. 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 2 feet? (Use the reference material in Section 1, the blue pages, of the Stability Data Reference Book)

To reduce stern drag to 2 feet, approximately 75 tons of ballast must be pumped into the forepeak. This is calculated using the trim formula, considering the change in trim required, the ship's MCT 1″ (Moment to Change Trim 1 inch) and LCF (Longitudinal Center of Flotation) obtained from the Stability Data Reference Book at the mean draft, and the forepeak's LCG.
