The height of the longitudinal metacenter of...

🔍 Key Concepts

• Longitudinal metacenter (M_L) and how its height is usually obtained from hydrostatic curves or a stability booklet for a specific displacement • Relationship between displacement and hydrostatic properties like KB, BM_L, and KM_L • How to read or interpolate from a hydrostatic table/curve at a given displacement

💭 Think About

• Think about what information you would normally look up in the vessel’s stability booklet or hydrostatic curves when asked for the height of the longitudinal metacenter at a specific displacement • Consider whether the value you’re looking for is typically measured from the keel (KM_L) or from some other reference, and make sure the answer choices make sense in that context • If you had tabulated hydrostatic data for the COASTAL DRILLER, how would you find or interpolate the correct KM_L value at 13,810 kips displacement?

✅ Before You Answer

• Confirm that you are dealing with longitudinal metacenter (M_L), not transverse metacenter • Verify whether the question is asking for the height above the keel (KM_L), not GM or BM alone • Check that the chosen value is consistent with typical magnitudes for KM_L on a vessel of this type and size; rule out any values that seem unreasonably high or low
