Question 1 of 2707066636eec28f7522a1c51d150

Your vessel's drafts are: FWD 27'-06", AFT 28'-02"; and the KG is 23.1 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the righting arm at 60° inclination.

🔍 Key Concepts

• Using the Selected Stability Curves (blue pages) for the correct mean draft/displacement • Understanding the relationship between KG, angle of heel (60°), and the righting arm (GZ) • Interpolating between curves or values if your exact KG is not tabulated

💭 Think About

• How do you find the correct page/curve in the blue pages based on the vessel’s mean draft or displacement? • Once on the right curve page, where do you read (or interpolate) the righting arm at 60° for the given KG? • If your exact KG is not listed, how do you interpolate between the two nearest KG curves to get the GZ at 60°?

✅ Before You Answer

• Be sure you used the mean draft from the given forward and aft drafts to select the proper curve/displacement • Confirm you are reading the GZ (righting arm) at 60°, not at another angle • If interpolation is needed, double‑check both the two KG values you used and your proportional calculation before choosing among A–D
