🔍 Key Concepts

• Displacement and TPI (tons per inch immersion) for the vessel at the starting draft • Location of No. 8 hatch in the longitudinal loading manual (its distance from midships) • How removing weight creates a trim moment that changes forward and aft drafts differently

💭 Think About

• From the initial drafts, estimate the vessel’s displacement and TPI from the Grand Haven manual. How many inches of mean draft change does removing 170 LT cause? • Is No. 8 hatch forward or aft of midships, and therefore will discharging from it tend to trim the bow up or the stern up? • After you find the change in mean draft and the change in trim, can you split the trim correctly between the forward and aft drafts to get the new readings?

✅ Before You Answer

• Verify the correct TPI at the vessel’s starting mean draft, not at a much lighter or deeper draft • Confirm the exact LCG (longitudinal center of gravity) position for No. 8 hatch from the manual and its distance from the LCB (longitudinal center of buoyancy) or midships reference • Double-check that your sign convention is consistent: when trim by the stern increases, the aft draft should increase and the forward draft should decrease, and vice versa
