Your vessel's drafts are: FWD 23'-10", AFT 26'-00". 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: 45 tons. Calculating the difference between the current trim and the desired 18-inch drag, then dividing by the moment to change trim one inch (MCTC), dictates that exactly 45 tons of ballast added to the forepeak fulfills the trim requirement.
