The DEEP DRILLER, at a draft of 60 feet, has a KGL of 55.4 feet and an LCG of 2.37 feet. What is the trim in feet?

🔍 Key Concepts

• Relationship between LCG (Longitudinal Center of Gravity) and trim • How center of flotation and KG/KGL relate to longitudinal stability and trim • Using a vessel’s hydrostatic curves or given coefficients to link LCG offset to trim in feet

💭 Think About

• Think about what it means when the LCG is a small distance off the vessel’s longitudinal center — how does that produce trim by the head or by the stern? • Consider whether the magnitude of 2.37 feet of LCG shift would create a small, moderate, or large trim for a vessel drafting 60 feet. • Ask yourself: does KGL (vertical center of gravity above keel) directly create trim, or does it affect another quantity that then influences trim?

✅ Before You Answer

• Be clear whether LCG is measured from midships or from another reference point in your formula. • Confirm whether KGL is needed in the trim calculation or if it’s only given to test your understanding of relevant vs. irrelevant data. • Check that the direction of trim (head vs stern) matches the direction of the LCG offset you are assuming.
