🔍 Key Concepts

• Trim and mean draft change when weight is added at the ends of the ship • How to use the Stability Data Reference Book (white pages) for the SS AMERICAN MARINER for trim problems • Relationship between tons per inch immersion (TPI) and moment to change trim (MCT)

💭 Think About

• First, think about what happens to the forward and aft drafts when you add weight all the way forward in the forepeak. Does the bow go deeper, the stern rise, or both? • Use the reference book to find the ship’s TPI and MCT at the given mean draft. How do these values help you calculate the change in mean draft and the change in trim? • Once you know the total change in trim, how do you divide that change between the forward and aft drafts based on the distance of the forepeak from the ship’s center of flotation?

✅ Before You Answer

• Be sure you are using data for the correct mean draft range in the Stability Data Reference Book white pages. • Double‑check the distance from the forepeak to the center of flotation (LCF) before computing the trimming moment. • After calculating new drafts, verify that the change in mean draft matches the total added weight using TPI, and that the forward draft change plus aft draft change equals the total trim change.
