Question 1 of 27070

🔍 Key Concepts

• Difference between actual KG and maximum allowable KG from the stability booklet or loading condition • Meaning of KGT (transverse) and KGL (longitudinal) and which one is used for intact transverse stability limits • How to interpret a KG limit line / table for a specific draft and wind condition

💭 Think About

• Ask yourself: In this question, are you being given the vessel’s current KG or the maximum allowable KG? Which value represents the stability limit? • Think about what "margin" usually means in stability problems: is it a difference between where you are now and a limit you must not exceed? • Consider which of the two given values (KGT or KGL) is appropriate for a wind heel / transverse stability requirement, and how you would compare the actual KG to the allowable KG.

✅ Before You Answer

• Identify clearly which number (39.0 ft or 38.6 ft) is the maximum allowable KG for this draft and wind condition. • Decide whether the vessel’s current KG is above or below that allowable value, and take the absolute difference between the two to find the margin. • Check that your final margin is a small, realistic difference in feet for a KG margin, not an extremely large separation that would imply a totally unsafe or impossible loading.
