1.3.1 The Rules
are framed on the understanding that craft will be properly loaded
and handled; they do not, unless it is stated or implied in the class
notation, provide for special distributions or concentrations of loading
other than those included in the approved Loading Manual. The Committee
may require additional strengthening to be fitted in any craft which,
in their opinion, would otherwise be subjected to severe stresses
due to particular features of the design, or where it is desired to
make provision for exceptional load or ballast conditions.
