Your vessel's drafts are: FWD 18'-09", AFT 19'-01". How much more cargo can be loaded to have the vessel down to the freeboard draft? (Use the information in Section 1, the blue pages, of the Stability Data Reference Book)
• Displacement and Deadweight from the hydrostatic tables in Section 1 (blue pages) • How to use the vessel’s draft to find displacement on the hydrostatic curves/tables • How to apply TPI/TPC (tons per inch/centimeter immersion) or displacement curves to additional draft down to freeboard draft
• From the current mean draft, what is the vessel’s present displacement according to the hydrostatic data? • What is the displacement at the freeboard draft shown in the Stability Data Reference Book, and how do you find the difference between the two? • If you need to refine the answer, how can you interpolate between table/curve values or use TPI/TPC to account for extra inches of draft?
• Verify the correct mean draft from the given forward and aft drafts before entering the tables • Confirm you are using the right column and units (feet vs meters, inches vs centimeters, saltwater vs freshwater) in the hydrostatic data • Make sure the difference in displacement (in tons) between current draft and freeboard draft aligns closely with one of the answer choices
