Stability calculations deal with a heeling moment which
is the product of a weight times a distance. Therefore, regulation 11(a)(i) requires the grain heeling moments
be furnished as part of the grain loading information. This is cumbersome
because each of several weights of grain would require a separate
grain heeling moment curve or tabulation for each cargo compartment.
To reduce the amount of data furnished, it has become the practice
in most grain loading booklets to provide curves or tables of volumetric
heeling moments in lieu of grain heeling moments. This reduces the
size of the booklet without loss of information because grain heeling
moment is simply volumetric heeling moment divided by the stowage
factor of whatever specific type of grain is being loaded. Therefore,
to interpret regulation 11(a)(i) so
as to conform with general practice, the following guideline is given.
