Subtracting the height of the center of gravity corrected for transverse free surface effects from the height of the transverse metacenter of a MODU yields __________.
• Meaning of transverse metacenter (M) and how it relates to initial stability • Definition of center of gravity corrected for free surface (Gᶠ or G′) and how free surface affects GM • Difference between distances measured from the keel (K) versus distances measured between G and M
• Ask yourself: when you subtract "corrected G" from "M", are you getting a distance from the keel, or the separation between these two points? • Which of the answer choices represent distances measured from K (the keel) and which represent the distance between G and M? • How does the phrase "corrected for transverse free surface effects" affect which symbol for G is appropriate in the final quantity?
• Identify which symbols in the options are explicitly measured from the keel (K). • Identify which symbol represents the metacentric height between G and M in the transverse direction. • Confirm that you are using the corrected G (after free-surface correction), not the original uncorrected G, when thinking about the notation.
