Which statement about the free surface correction is TRUE?
AI Explanation
The correct answer is A) It is obtained by dividing the free surface moments by 12 times the volume of displacement.
This is the correct answer because the free surface correction is calculated by dividing the free surface moments (the moment of inertia of the free surface) by 12 times the volume of displacement. This correction accounts for the reduction in righting arm caused by free surface effects within tanks and compartments.
The other answer choices are incorrect because B) the free surface correction is subtracted from the uncorrected GM to arrive at the corrected available GM, C) the free surface correction is not subtracted from the longitudinal moments, and D) the free surface correction is not obtained by dividing the free surface by the vertical moments.
