Question 1 of 2707066636eec28f7522a1c51d111

A vessel's drafts are: FWD 19'-00", AFT 17'-02". How much more cargo can be loaded to have the vessel down to the freeboard draft? (Use the information in Section 1, the blue pages, of the Stability Data Reference Book)

Question 1 of 27070

🔍 Key Concepts

• Trim and mean draft when forward and aft drafts are different • Using deadweight scale / capacity curves in the Stability Data Reference Book • Relationship between change in draft and tons loaded (TPC or MT1"/cm)

💭 Think About

• First, what is the correct mean draft based on the forward and aft drafts given? • Once you know the mean draft, what draft does the freeboard mark correspond to in the blue pages, and what is the difference in draft between your current mean draft and the freeboard draft? • How do you convert that difference in draft into tons of cargo using the data tables (not a simple linear guess)?

✅ Before You Answer

• Be sure you are using the correct hydrostatic table for the vessel’s present draft range • Carefully read the units: is the table giving you tons per inch (TPI/TPC) or total displacement for each draft? • Confirm whether you must account for trim effects or if the question assumes parallel sinkage using mean draft only
