Question 1 of 27070

Your vessel's existing draft is FWD 17'-03", AFT 18'-09". Using the Guidance Manual for Loading M.V. Grand Haven, determine the new draft if 450 long tons are loaded in No. 16 hatch.

🔍 Key Concepts

• Use of a vessel’s trim and stability (loading) manual when adding weight in a specific hatch • How adding weight at a known longitudinal location changes draft forward and aft • Difference between a parallel sinkage (no trim change) vs. a change in trim

💭 Think About

• From the existing drafts, what is the current trim (difference between aft and forward drafts)? • When you load 450 LT in No. 16 hatch, is that position forward or aft of midships/LCB, and therefore will it tend to trim the vessel by the bow or by the stern? • Using the loading manual tables, how much mean draft increase and trim change per 100 LT (or per LT) does 450 LT in No. 16 hatch create, and how do you turn those into separate FWD and AFT draft changes?

✅ Before You Answer

• Confirm you are using the correct table/column for No. 16 hatch and for the displacement (or condition) closest to the vessel’s present state • Check the sign of trim (by the bow vs by the stern) when applying the change to forward and aft drafts • Recalculate final drafts by starting from initial drafts and adding/subtracting the exact inches of change at each end; verify your arithmetic in inches and fractions carefully
