Question 1 of 27070

Q

Your vessel's drafts are: FWD 24'-07", AFT 25'-09"; and the KG is 23.2 feet. What is the righting moment when the vessel is inclined to 45°? (Use the reference material in Section 1, the blue pages, of the Stability Data Reference Book)

🔍 Key Concepts

• Cross curves of stability (KN curves) for the given drafts • Relationship between KG, GZ (righting arm), and heel angle • How to get righting moment from displacement and GZ

💭 Think About

• From the given drafts, which table in the blue pages do you use first, and what key value do you read from it? • Once you know the vessel’s displacement and the KN value at 45°, how do you adjust that KN value for the given KG to find GZ? • After finding GZ at 45°, what simple multiplication gives you the righting moment, and in what units?

✅ Before You Answer

• Make sure you are using the correct displacement that matches BOTH the forward and aft drafts given in the question • Check that you are using the KN at 45° from the correct curve/table before applying any KG correction • Confirm that your final step uses Righting moment = Displacement × GZ, and that your units give an answer in foot-tons
