Q

Your vessel's existing draft is FWD 14'-00", AFT 16'-00". Using the Guidance Manual for Loading M.V. GRAND HAVEN, determine the new draft if 350 long tons are discharged from No. 13 hatch.

🔍 Key Concepts

• Trim and draft change when weight is removed from a specific hatch • How LCF (Longitudinal Center of Flotation) and distance from LCF affect changes in forward and aft drafts • Using the vessel’s TPc (Tons per Centimeter immersion) or TPC/TPI data from the Guidance Manual

💭 Think About

• Where is No. 13 hatch located relative to midships and the Longitudinal Center of Flotation—closer to the bow or the stern? How will removing weight there change trim? • After removing 350 LT, will the overall mean draft increase or decrease, and by about how much based on the vessel’s TPC/TPI? • Once you know the change in mean draft and the trimming moment, how will the draft change be distributed between the forward and aft drafts?

✅ Before You Answer

• From the Guidance Manual, identify the longitudinal position (LCG) of No. 13 hatch and the LCF for the current draft condition • Confirm the correct TPC/TPI value at or near the starting mean draft of 15 ft and apply it over 350 LT removed • Check that your final drafts keep the vessel’s mean draft less than 15 ft and the aft draft still deeper than the forward draft (same trim by stern)
