Your vessel's drafts are: FWD 21'-08", AFT 24'-02". 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 15 inches? (Use the selected stability curves in Section 1, the blue pages, of the Stability Data Reference Book)

Question

Accepted Answer

Option C: 82 tons. Calculating the initial trim and applying the vessel's moment to change trim one inch (MCTC) from the hydrostatic tables determines that shifting or adding 82 tons of ballast into the forepeak alters the trim to the desired 15-inch drag.
