The DEEP DRILLER, at a draft of 58 feet, has VM of 900,000 ft-tons, and FSMT of 20,000 ft-tons. What is the KGT?

Correct Answer: Option A — 51.6 feet

Transverse center of gravity (KGT) includes transverse free surface corrections. Divide total vertical moments (VM) plus transverse free surface moments (FSMT) by the displacement corresponding to a 58-foot draft, producing the correct transverse center of gravity height of 51.6 feet as tabulated in the stability manual.
