Question 4325 Deck General

The correct answer is A) -6,716 ft-long tons. The lightweight longitudinal moments refer to the overturning moments acting on a vessel due to its own weight distribution. For the DEEP DRILLER, the lightweight longitudinal moment is calculated to be -6,716 ft-long tons, which represents the net downward force acting at the vessel's center of gravity. The other options are incorrect because B) 9,733 ft-long tons and C) 680,914 ft-long tons do not accurately reflect the lightweight longitudinal moment for the DEEP DRILLER, and D) -5,937 ft-long tons is a different value than the correct answer of -6,716 ft-long tons.
