We have computed the moment for each weight but, obviously,
those having their centres of gravity at the same height above the keel
could be slumped together and so reduce the number of items.

CARGO AND TRIM.
The ship supported as she is by fluid pressure is free to incline in
any direction under the action of forces. The forces acting on the
ship and the effects produced when dealing with inclinations in a fore-
and-aft direction are similar to those just described for transverse
inclinations. In Figure 38 B denotes the longitudinal position of the
centre of buoyancy (L.C.B.) and (zthe longitudinal position of the centre
of gravity (L.C.G.). It should be observed that in any vessel the longi-
tudinal metacentric height (L.G.M.) is considerably greater than the
transverse metacentric height (G M) and consequently the ship is very
much strffer in a fore-and-aft direction than transversely. The ship
will always be stable in a fore-and-aft direction as it is practically
impossible to raise the C. of G. above the longitudinal metacentre.
