534. The DEEP DRILLER, at 60.0 feet draft in sea water, has VM = 974,441 foot-long tons, LM = 40,301 foot-long tons, TM = 3 foot-long tons, FSML = 30,572 foot-long tons, and FSMT = 18,732 foot-long tons. What is the longitudinal free surface correction to KG?

The longitudinal free surface correction to KG is calculated by dividing the longitudinal free-surface moment (FSML) by the vessel's displacement; in this case, FSML is 30,572 foot-long tons and the displacement at 60.0 feet draft is approximately 18,100 foot-long tons, resulting in a correction of 1.69 feet.
