🔍 Key Concepts

• Maximum allowable KG (KGL) vs actual KG (KGT) – understand what each represents • How to interpret the word margin in stability problems (difference between a limit and an actual value) • Basic subtraction of two vertical distances measured from the same reference (usually the keel)

💭 Think About

• Which of the two given values (KGT = 39.1 ft and KGL = 39.9 ft) is the limiting value and which is the current condition? • If you want to know the safety margin between where you are and the limit, what simple operation do you perform between those two numbers? • After you find that numerical difference, which answer choice matches it exactly?

✅ Before You Answer

• Confirm that KGT is the vessel’s current KG at that draft and condition, not the limit • Confirm that KGL is the maximum allowable KG from the stability criteria, not the actual condition • Be sure you subtract in the correct order so that the margin comes out as a small positive number, not a large unrealistic value
