The COASTAL DRILLER, in field transit at a draft of 10 feet 0 inches with winds less than 70 knots, has a KGT of 39.0 feet and a KGL of 38.6 feet. The margin on the maximum allowable KG is __________.

Correct Answer: Option D — 26.4 feet

Evaluating stability during field transit with favorable weather (winds under 70 knots) involves comparing actual transverse and longitudinal center of gravity heights against the operational limits. The large positive difference between the allowable threshold and the actual KG results in a stability margin of 26.4 feet.
