3.1.1 An inclining test should be required for
the first unit of a design, when as near to completion as possible,
to determine accurately the light ship weight and position of centre
of gravity. The test should be carried out in the presence of an officer
of the Administration or a duly authorized person or representative
of an approved organization.
3.1.2 For successive units of a design, which
are identical with regard to hull form and arrangement with the exception
of minor changes in machinery or outfit, detailed weight calculations
showing only the differences of weight and centres of gravity should
be satisfactory provided the accuracy of the calculations is confirmed
by a deadweight survey.
3.1.3 The results of the inclining test, or deadweight
survey and inclining experiment adjusted for weight differences, should
be indicated in the Operating Manual.
