When holds are loaded in combination, void spaces exist
beneath the deck which are within the stow, as shown in figure 1 for a “filled" hold
or figure 2 for a “partly
filled" hold.

In the case of figure 1,
it is not permissible to reduce the grain heeling moment by placing
a saucer or a bundle within the coaming of the upper hatchway. Similarly,
in the case of figure 2, if the
stability of the ship cannot tolerate the grain heeling moment of
the arrangement shown, it is not permissible to eliminate the grain
heeling moment by securing the upper surface by means of strapping
or lashing. The reason is that, in both situations, the redistribution
of some of the void spaces from beneath the lower decks to the upper
compartment (as described in part B, section
II(C), has the potential for dropping the bundle or saucer
from the confines of the hatch coaming, or loosening the strapping
arrangement and thereby diminishing or defeating their effectiveness
as a mechanism for reducing the grain heeling moment.
