Because of the presence of 75 knot winds, the DEEP DRILLER is at survival draft. KGT is 3.24 feet less than the maximum allowed. What is the value of GMT?

🔍 Key Concepts

• KG (height of center of gravity above keel) vs KGT (allowable/transverse KG limit) • Relationship between maximum allowable KG and minimum required GM for survival conditions • How a KG that is lower than the maximum allowable affects the actual GM (GMT)

💭 Think About

• Think about what it means when the vessel’s actual KG is a certain distance below the maximum permitted KG for that draft and condition. How does that change GM? • On most stability curves, when KG decreases (center of gravity goes down), what happens to GM numerically? Is GM larger or smaller? • If GM were exactly at the minimum allowed value, what would be the relationship between KG and KGT? Now, if KG is 3.24 ft below KGT, how far above the minimum is GM?

✅ Before You Answer

• Be clear on whether KGT in this question represents the maximum allowable KG for survival draft or the actual KG; interpret the wording carefully. • Recall or note that GM = KM − KG and that the ‘maximum allowable KG’ typically corresponds to a minimum GM value on the stability criteria curve. • Check which answer choice matches a GM that is the minimum allowed GM plus 3.24 ft, not just 3.24 ft by itself.
