Your vessel's existing draft is FWD 24'-08", AFT 25'-04". Using the Guidance Manual for Loading M.V. GRAND HAVEN, determine the new draft if 180 long tons are loaded in No. 23 hatch.
• Using the Guidance Manual tables specific to M.V. GRAND HAVEN for added weight in each hatch • How loading weight away from midships affects both mean draft and trim (bow vs stern) • Converting decimal inches or fractions from the table into feet–inches–fractions and combining them with the original drafts
• Find the table line for No. 23 hatch and the column for the weight closest to 180 long tons. What does the table show for change in draft forward and change in draft aft for that loading? • After you get the changes, how do you add or subtract them from the original drafts (FWD 24'-08", AFT 25'-04") depending on whether the bow or stern goes deeper or rises? • When you adjust the drafts, which choice matches both your new forward draft and new aft draft, including the fractional inches?
• Verify from the manual whether loading in No. 23 hatch causes the vessel to trim by the bow or by the stern. • Check that the mean draft change implied by your chosen forward and aft drafts is consistent with adding 180 long tons as shown in the manual (e.g., via TPI/TPM or tabulated values). • Carefully recalculate feet–inches–fractions, making sure 12 inches = 1 foot and that fractional inches are handled correctly before matching to the answer choices.
