Question 1 of 2707066636eec28f7522a1c51d13b

Your vessel's drafts are: FWD 22'-03", AFT 22'-09"; and the KG is 24.4 feet. What is the righting moment when the vessel is inclined to 15°? (Use the reference material in Section 1, the blue pages, of the Stability Data Reference Book)

Question 1 of 27070

🔍 Key Concepts

• Using vessel trim (difference between forward and aft drafts) to find the correct hydrostatic data page in the Stability Data Reference Book • Reading GZ (righting arm) at a given angle from the stability curve, then converting that into righting moment using vessel displacement • Understanding the relationship: Righting Moment = Displacement × GZ

💭 Think About

• How do you determine the vessel’s displacement and GZ at 15° using the drafts and the reference book tables? • Once you have GZ at 15°, what simple multiplication must you perform with the ship’s displacement to obtain the righting moment? • How does the given KG affect which GZ curve or table you should use in the stability data?

✅ Before You Answer

• Verify you are using the correct displacement that corresponds to the actual drafts (not a lightship or deadweight figure). • Confirm you have read GZ at exactly 15° from the correct curve/table that matches the given KG. • Before picking an answer, quickly estimate whether your moment size (Displacement × GZ) is in the thousands of foot-tons range matching one of the choices.
