The derivation of this formula is similar to that for ®nding the transverse BM.
For a rectangular water-plane area:
IL BL3
where and
12
L the length of the water-plane
B the breadth of the water-plane Thus, for a vessel having a rectangular water-plane:
BML BL3 12V
BML IL V
BL3 12V
BL3 12 L B d
BML L2 12d
For a box-shaped vessel:
