Because of the presence of 75 knot winds, the DEEP DRILLER is at survival draft. KGT is 3.24 feet less than the maximum allowed. What is the value of GMT?

Correct Answer: Option A — 5.32 feet

Transverse metacentric height corrected for free surface effects (GMT) is derived directly from hydrostatic properties. When KGT is known relative to maximum allowances, standard stability calculations determine GMT through direct geometric subtraction from the height of the transverse metacenter (KMT).
