Question 1 of 2707066636eec28f7522a1c51d130

Your vessel's drafts are FWD 19'-03", AFT 21'-07". Use the information in Section 1, the blue pages, of the Stability Data Reference Book to determine the final drafts if 142 tons of fuel are pumped 86 feet aft.

Question 1 of 27070

🔍 Key Concepts

• Trimming moment when weight is shifted longitudinally • How to use the vessel’s MT1" (moment to change trim 1 inch) from the Stability Data Reference Book • Relationship between total change in trim and how much the bow and stern drafts change

💭 Think About

• First, calculate the trimming moment created by pumping 142 tons of fuel 86 feet aft. What is the basic formula for a trimming moment? • Once you know the total change in trim in inches, how do you use that to find how much the forward and aft drafts change individually? Does all the change happen at one end? • Compare each answer choice: which one shows the bow getting shallower and the stern getting deeper by an amount that matches your computed change in trim?

✅ Before You Answer

• Be sure you are using the correct displacement and MT1" from the blue pages that match the vessel’s starting condition. • Watch your signs and direction: shifting weight aft should make the aft draft increase and the forward draft decrease. • Confirm that the change in trim (inches) you compute is consistent with the difference between the new aft and forward drafts shown in the choices.
