3.1 Inclining test
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.
