With the basics of GM = KM - KG
Note: GM is properly called metacentric height
GML = KML - KGL
64.92-55.89=9.03
ANS: DELTA
Yes, this one could not wait until March 16th. It is sad most Merchant Marine Academies around the world skip over this type of question if it mentions the vessels in the Offshore Oil Industry.
