The SS AMERICAN MARINER has drafts of: FWD 13'-05", AFT 21'-03". Use the white pages of the Stability Data Reference Book to determine the drafts if you ballast the forepeak with 88 tons of seawater.

🔍 Key Concepts

• Trim and drafts – how adding weight at one end of the vessel affects forward and aft drafts • Using the white pages for SS AMERICAN MARINER in the Stability Data Reference Book to find trim changes due to added weight in a specific tank (forepeak) • Converting tons of ballast in a specific tank into changes in draft at the forward and aft perpendiculars

💭 Think About

• First, from the white pages, identify the correction factors or tables that show how many inches of trim or draft change occur when you add weight in the forepeak tank. Which table applies here? • Think about the direction of trim: adding weight forward will cause the bow to go deeper and the stern to rise. About how much change forward and aft would you expect for 88 tons? • After finding the basic change in trim from the tables, how do you convert that trim into separate forward and aft draft changes starting from the original drafts?

✅ Before You Answer

• Verify you are using the correct ship (SS AMERICAN MARINER) and the correct tank (forepeak) tables in the white pages • Double-check the total change in mean draft after adding 88 tons against the vessel’s TPI (tons per inch immersion) or equivalent data given • Ensure the signs of draft change make sense: forward draft should increase and aft draft should decrease when adding ballast at the extreme forward end
