593. The DEEP DRILLER is loaded as shown in the Sample Load Form #1 (Transit). What is the new metacentric height corrected for longitudinal free surface effects if the entire contents of salt water ballast 1anks 1P and 1S are discharged? (Use KML = 348.58)

Discharging ballast tanks 1P and 1S reduces free surface effects and changes the vessel's displacement and center of gravity. Applying the stability relation GMl (corrected) = KML − KG − (ΣFSM/Δ) using data from Sample Load Form #1 yields a corrected metacentric height of 279.37 feet.
