Your vessel's drafts are: FWD 22'-03", AFT 22'-09"; and the KG is 23.2 feet. What is the righting moment when the vessel is inclined to 30? ? (Use the reference material in Section 1, the blue pages, of the Stability Data Reference Book)

🔍 Key Concepts

• Righting arm (GZ) curves in the Stability Data Reference Book • Relationship between displacement, GZ, and righting moment • How trim and draft affect the displacement used in calculations

💭 Think About

• From the drafts given, what is your first step before you can find any righting moment? • Once you have the vessel’s displacement, where in the blue pages can you find the GZ value for 30° at the given KG? • After you obtain GZ, how do you combine it with displacement to get a righting moment, and what are the correct units for the result?

✅ Before You Answer

• Be sure you are using the correct displacement that corresponds to the given drafts (FWD and AFT) • Confirm that you are reading the GZ value at 30° that matches the vessel’s KG = 23.2 ft • When you multiply, verify your units so the final answer is in foot-tons, not foot-pounds or another unit
