Question 1 of 2066636eec28f7522a1c51cc42

The sailing drafts are: FWD 16'-06", AFT 17'-04" and the GM is 2.6 feet. Use the information in Section 1, the blue pages, of the Stability Data Reference Book, to determine the available righting arm at 15° inclination.

🔍 Key Concepts

• Difference between GM and GZ (righting arm) and how to move from one to the other • How to use the Stability Data Reference Book – Section 1 (blue pages) to find GZ at a given heel angle • Effect of trim (different forward and aft drafts) on which GZ curve or correction you should use

💭 Think About

• First, decide if you use GM directly to get GZ, or if you should be reading a GZ value from a curve in the blue pages – what do the instructions at the top of Section 1 say? • Look at how the loading condition (displacement and KG/GM) in the blue pages matches your vessel’s condition. Are you interpolating between curves or using a GM correction? • At 15° of heel, what does the curve or table give you, and do you need to apply any correction based on the actual GM given in the question?

✅ Before You Answer

• Confirm you are using the correct GZ curve or table for the given drafts (displacement condition). • Verify whether the blue pages procedure tells you to apply a GM-based correction to GZ at small angles, and how to do it. • Re-check units: the final answer must be in feet of righting arm (GZ), not in meters or in GM.
