Because of the presence of 75 knot winds, the DEEP DRILLER is at survival draft. KGL is 1.24 feet less than the maximum allowed. What is the value of GML?

Correct Answer: Option D — 1.39 feet

Longitudinal metacentric height (GML) is derived from the vertical center of gravity and the longitudinal metacenter. When operating at survival draft with a KGL deficit of 1.24 feet under 75 knot winds, standard stability formulas establish GML at 1.39 feet.
