While underway in a field move with the lower hulls awash, a semisubmersible has an allowable KG of 63.69 feet; KMT is 65.12 and KML is 64.92. The KGT is 56.13 and KGL is 55.89. What is the GML?

AI Explanation
The correct answer is D) 9.03 feet. To calculate the GML (Transverse Metacentric Radius), we use the formula: GML = KML - KG. Given the values provided, GML = 64.92 - 55.89 = 9.03 feet. The other options are incorrect because: A) 1.43 feet is the difference between KMT and KML, not the GML. B) 7.56 feet is the difference between KMT and KG, not the GML. C) 7.80 feet is the difference between KMT and KGT, not the GML.
