loading may be computed. The procedure is to consult the cargo plan
and ascertain the height of the centre of gravity above the keel (K G)
of each superimposed block of cargo and also its weight. The position
of the centre of gravity (V.C.G.) will be approximately near the middle
line of the block of cargo when it -is of equal density throughout. A
simple example will perhaps indicate the principle.

Example.—A vessel's light displacement is 1200 tons and initial
centre of gravity 10 feet above the keel (K G). She loads 3000 tons of
coal in her lower holds, the estimated centre of gravity being 14 feet; and
1000 tons in her 'tween decks, the centre of gravity being 24 feet. If
her metacentre at load draught is 17 feet above ke*el (KM), required
her G M when loaded.
