A vessel's drafts are FWD 20'-08", AFT 20'-10". Use the information in Section 1, the blue pages, of the Stability Data Reference Book to determine the final drafts if 195 tons of cargo are discharged 76 feet forward of amidships

Question 1 of 27070

🔍 Key Concepts

• Trimming moments caused by shifting or discharging weights longitudinally • Relationship between MT1" (Moment to Trim 1 inch) and change in draft at the bow and stern • Sign convention for moments forward and aft of amidships when cargo is discharged

💭 Think About

• What happens to the vessel’s center of gravity when weight is removed forward of amidships – does the ship tend to trim by the bow or by the stern? • How do you convert the weight and its distance from amidships into a trimming moment, and then into inches of trim using the MT1" from the blue pages? • Once you know the total trim change, how is that trim split between the forward and aft drafts on a ship of this length?

✅ Before You Answer

• Be sure you are using the correct sign (+/−) for a moment occurring forward of amidships when weight is discharged, not loaded. • Confirm that you are using the proper MT1" for the vessel’s mean draft from Section 1 of the Stability Data Reference Book. • After applying the trim change, verify that the mean draft change matches the change in total displacement from discharging 195 tons.
