Question 1 of 27070

🔍 Key Concepts

• Difference between transverse KG (KGT) and longitudinal KG (KGL) and which one relates to maximum allowable KG for stability in heavy weather • Understanding that margin on maximum allowable KG is the difference between maximum permissible KG and actual KG (or a similar pair of values) • How to correctly subtract and compare decimal feet values (e.g., 38.7 ft vs 38.2 ft) and relate the result to the answer choices

💭 Think About

• Ask yourself: which of the two given values (KGT or KGL) would you compare to a maximum allowable KG for transverse stability in strong winds? • Once you decide which value to use, think: is the margin based on a direct difference between two KG-related numbers, or does it involve something more complex? • Look at the numerical values provided and the answer choices: which operation on the given KGs produces a small margin (on the order of a couple of feet)?

✅ Before You Answer

• Be sure you are using the correct KG (transverse vs longitudinal) when thinking about maximum allowable KG under wind conditions. • Confirm that the margin refers to a difference in feet and not a percentage or ratio. • After you do your subtraction, check that your result matches one of the choices both in value and in units (feet).
