624. The DEEP DRILLER, loaded as shown in the Sample Load Form #4 (Drilling), discharges a non-liquid load of 275.8 long tons from a position 130 feet above the keel, 40 feet forward of amidships, and 30 feet to port of the centerline. What is the new KGL?

Removing a weight high above the keel reduces the ship's vertical moment and displacement, resulting in a new KGL of 54.32 feet. The KGL calculation uses the formula KGLnew = (W * KGLold — w * KGw) / (W — w), where W is the original displacement, w is the removed weight, and KGw is the weight's vertical position. Only the vertical position of the removed weight affects KGL; longitudinal and transverse positions are irrelevant.
