Using the Guidance Manual for Loading the M.V. Grand Haven, determine the amount of ballast required in tank No. 3 (P & S) to maintain drafts of 17'-00" forward and 22'-06" aft for a vessel loaded with grain which has a test weight of 34 lbs.

Question 1 of 27070

🔍 Key Concepts

• Load/displacement curves and how added ballast changes drafts forward and aft • Effect of grain test weight (34 lbs) on cargo weight and resulting trim • Using the vessel’s loading guidance manual tables to interpolate between conditions

💭 Think About

• How does adding equal amounts of ballast in No. 3 P & S (a midships tank) affect the trim versus the mean draft? • Which table in the Grand Haven loading manual lets you match a specific forward and aft draft to a required ballast amount? • How does the lighter grain (34 lbs test weight) change the vessel’s displacement compared with standard grain, and what does that imply about the ballast needed?

✅ Before You Answer

• Verify the grain cargo weight using the test weight of 34 lbs and the given stowage volume from the manual • Confirm the longitudinal position of No. 3 P & S relative to LCF/LCB to understand its effect on trim • Match the calculated displacement and desired 17'-00" F / 22'-06" A drafts to the closest loading condition in the manual and check which ballast entry corresponds to that condition
