Question 1 of 27070

🔍 Key Concepts

• Meaning of KGT and KGL in stability tables (they represent limiting vertical centers of gravity) • Definition of margin on maximum allowable KG (relationship between actual KG and the limiting/maximum KG) • How to choose which limiting KG applies when you are given more than one value (more restrictive value)

💭 Think About

• Ask yourself: do KGT and KGL represent the actual KG of the vessel, or the maximum permitted KG under different criteria? • Which of the two given KG limits is more restrictive, and why is that the one that controls the margin? • Once you know the controlling maximum allowable KG, how is the margin to that limit calculated from the vessel’s present KG shown (or implied) in the stability information for this transit condition?

✅ Before You Answer

• Be clear on the difference between actual KG and maximum allowable KG from the stability tables • Confirm whether the smaller or larger of KGT and KGL governs the condition for this question • Before choosing an answer, mentally compute: margin = (controlling maximum allowable KG) − (actual KG) and compare that value to the options given
