Question 4890 Deck General

The correct answer is C) 50.79 feet. To arrive at this answer, you need to calculate the new height of the center of gravity (VCG) after discharging the contents of drill water tanks 6 and 7. This involves accounting for the changes in the vessel's weight and longitudinal free surface effects. The provided information and calculations indicate that the new VCG is 50.79 feet, making answer C the correct choice. The other answer choices are incorrect because they do not accurately reflect the new VCG after the specified change in loading condition. Without the detailed calculations, it is difficult to determine the exact reasons why the other options are wrong, but the correct answer of 50.79 feet is the result of properly applying the relevant principles and regulations for stability and center of gravity calculations.
