A vessel is limited to a maximum draft of 25'-11". The present drafts are: FWD 24'-10", AFT 23'-02". How much more cargo can be loaded and where should it be located if a drag of 18 inches is desired? (Use the reference material in Section 1, the blue pages, of the Stability Data Reference Book)

Correct Answer: Option C — 690 tons 62 feet aft of the tipping center
To achieve a specific drag, calculate the required change in trim and the corresponding longitudinal moment. Using the vessel's stability data, determine the weight to be added and its position relative to the tipping center. Placing 690 tons 62 feet aft of the tipping center satisfies the required 18-inch trim.
