Question 1 of 27070

The DEEP DRILLER has a KGL of 53.16 feet while at a draft of 58.0 feet. Although there are no environmental forces, trim is 2.0 feet by the stern. What is the value of LCG?

🔍 Key Concepts

• Relationship between KGL (height of G above keel) and vertical position of the waterline/draft • Definition of LCG (longitudinal center of gravity) and how it relates to trim by the stern when no external forces act • How a small trim by the stern affects the longitudinal position of G relative to the midships point or a reference point

💭 Think About

• If the vessel is trimmed 2.0 feet by the stern with no external forces, what does that tell you about where the center of gravity lies relative to the center of flotation? • How does changing draft or trim influence the LCG, and which of the given options is most consistent with a slight stern-down trim? • Given KGL and the draft, which of those values is most helpful for this question, and which might be a distraction?

✅ Before You Answer

• Be clear on the definition of LCG: distance measured along the length, not vertically • Confirm that you are not mixing up KGL (vertical) with LCG (longitudinal) – they are independent coordinates of the same point G • Check that the magnitude of the chosen answer is reasonable for a small trim of 2.0 feet on a unit of this size (think about whether LCG must be just slightly off a reference point, not extremely far)
