Question 1 of 27070

Your vessel's existing draft is FWD 17'-04", AFT 18'-08". Using the Guidance Manual for Loading M.V. GRAND HAVEN, determine the new draft if 765 long tons are discharged from No. 7 hatch.

🔍 Key Concepts

• Use the vessel’s trim and stability data from the Guidance Manual for M.V. GRAND HAVEN (TPI/MT1, LCF, LCG, MTC, etc.) • Understand how discharging weight at a specific longitudinal location affects both mean draft and trim • Convert feet-inches correctly, especially when dealing with fractions of an inch

💭 Think About

• First, decide: will discharging 765 LT make the ship lighter or heavier overall, and should the mean draft increase or decrease? Eliminate any options that don’t match that basic effect. • Where is No. 7 hatch in relation to midships? Think about whether removing weight there will cause the bow to rise or sink relative to the stern. • After you estimate the direction of trim change, check which answer choice shows the forward and aft drafts moving in the correct directions and by a realistic amount.

✅ Before You Answer

• Verify from the manual the longitudinal position of No. 7 hatch relative to midships and the LCF (Longitudinal Center of Flotation). • Use the correct TPI (tons per inch immersion) to estimate the change in mean draft for 765 LT removed, and see which option is closest. • Check that the forward and aft draft changes are consistent with the sign and magnitude of the calculated trim (using MT1 or MTC data), not just the mean draft change.
