Question 4409 Deck General

The correct answer is C) maximum allowable KG. Stability for a vessel in transit is primarily determined by the vessel's center of gravity (KG) relative to the maximum allowable KG for the vessel's condition. As long as the actual KG does not exceed the maximum allowable KG, the vessel's stability is considered acceptable. This is a fundamental stability requirement outlined in the Coast Guard regulations for commercial vessels. The other answer choices are incorrect because they refer to other stability parameters (KML, KMT, GML, GMT, and righting arm) which are not the primary determinant of stability for a vessel in transit.
