Which statement about the free surface correction is TRUE?
A. It is added to the uncorrected GM to arrive at the corrected available GM.
B. It is obtained by dividing the free surface moments by 12 times the volume of displacement.
C. It is obtained by dividing the total free surface by the total vertical moments.
D. It is subtracted from the total longitudinal moments before dividing by displacement to find LCG.
The best answer is B. Do you agree or disagree?
ReplyDeleteFree Surface Correction = r(LxWxWxW/12xDisplaced Volume)
Where:
r = ratio of SG of liquid in the Tank to that of the water the vessel is floating
L = Length of tank
W = Width of tank
