A vessel's drafts are FWD 19'-02", AFT 23'-10". Use the information in Section 1, the blue pages, of the Stability Data Reference Book to determine the final drafts if 98 tons of fuel is pumped 116 feet forward.

Question 1 of 27070

🔍 Key Concepts

• Trimming moment when weight is shifted longitudinally • Using the vessel’s MT1" (moment to change trim 1 inch) from the Stability Data Reference Book • How moving weight forward affects forward and aft drafts

💭 Think About

• First, decide whether the vessel will trim more by the bow or by the stern when fuel is pumped forward. What does that do to the forward and aft drafts? • Calculate the trimming moment by multiplying the weight moved by the distance moved. Then relate that to MT1" to find the total change in trim in inches. • Once you know the total change in trim, think about how it splits between forward and aft drafts on a conventional ship: does the bow take the full change, or is it shared between both ends?

✅ Before You Answer

• From the blue pages, be sure you are using the correct displacement and MT1" that match the vessel’s starting condition. • Confirm your unit consistency: tons, feet, and inches of trim must be handled correctly. • After estimating the new drafts, check that the sum of changes at the bow and stern equals the total trim change you computed.
