🔍 Key Concepts

• Using the white pages of the Stability Data Reference Book for the SS AMERICAN MARINER to find how added weight in a specific tank affects trim and drafts • Understanding how adding weight at the forepeak (far forward) will generally change the bow and stern drafts • Distinguishing between change in mean draft (overall sinkage) and change in trim (difference between forward and aft drafts)

💭 Think About

• When you add 83 tons to the forepeak, which end of the vessel is that weight closest to, and what does that usually do to the forward draft versus the aft draft? • From the white pages, find the trim and sinkage effect per ton (or per 10 tons, etc.) for the forepeak tank. How do you apply those factors to 83 tons to get new drafts? • After finding the change in mean draft and change in trim, how do you correctly split the trim change between the forward and aft drafts to get the final values?

✅ Before You Answer

• Verify you are using the correct tank (forepeak) line from the SS AMERICAN MARINER tables, not a midship or aft tank • Confirm that you have calculated both change in mean draft and change in trim, and that the signs (increase/decrease forward vs aft) make physical sense • Check the final answer choice to be sure the forward draft increases more than, equal to, or less than the aft draft in a way that matches adding weight at the forepeak
