Q

Your vessel's existing draft is FWD 25'-04", AFT 24'-08". Using the Guidance Manual for Loading M.V. GRAND HAVEN, determine the new draft if 634 long tons are discharged from NO. 19 hatch.

🔍 Key Concepts

• Trim and mean draft changes when weight is added or removed • Using TPC (tons per centimeter immersion) or tons per inch to find how much the drafts change with a given weight • How longitudinal center of flotation (LCF) and the location of NO. 19 hatch affect trim

💭 Think About

• First, think about whether discharging cargo will make the vessel sit deeper or lighter in the water. Should the drafts increase or decrease? • Consider whether NO. 19 hatch is located forward or aft of the vessel’s LCF. Will removing weight there tend to trim the vessel more by the bow or by the stern? • After changing the mean draft for the 634 tons discharged, think about how that change will split between the forward and aft drafts based on the trim effect.

✅ Before You Answer

• Verify from the Guidance Manual the TPI/TPC (how many tons change the draft 1 inch or 1 cm) at the original mean draft • Check the fore-and-aft location of NO. 19 hatch relative to midships or LCF in the manual • After you estimate the new drafts, confirm that the change in mean draft and the change in trim are both consistent with removing 634 tons at that location
