The correct answer is A) 0.00 on the centerline. When a vessel is level at a draft of 58 feet and there are no environmental forces acting on it, the transverse center of gravity (TCG) will be 0.00 on the centerline. This is because in the absence of external forces, the vessel's center of gravity will be directly over the keel, resulting in a TCG value of 0.00. The other options (B, C, and D) are incorrect because they indicate the TCG is forward of amidships, which would only be the case if environmental forces, such as wind or waves, were acting on the vessel and causing it to list or trim.
