7.1 Application

  7.1.1 footnote Every passenger ship regardless of size and every cargo ship having a length, as defined in the International Convention on Load Lines, 1966, of 24 m and upwards, should be inclined upon its completion and the elements of its stability determined.footnote

  7.1.2 footnote Where any alterations are made to a ship so as to materially affect the stability, the ship should be re-inclined.footnote

  7.1.3 footnote At periodic intervals not exceeding five years, a lightweight survey should be carried out on all passenger ships to verify any changes in lightship displacement and longitudinal centre of gravity. The ship should be re-inclined whenever, in comparison with the approved stability information, a deviation from the lightship displacement exceeding 2% or a deviation of the longitudinal centre of gravity exceeding 1% of L is found, or anticipated. footnote

  7.1.4 footnote The Administration may allow the inclining test of an individual ship as required by paragraph 7.1.1 to be dispensed with provided basic stability data are available from the inclining test of a sister ship and it is shown to the satisfaction of the Administration that reliable stability information for the exempted ship can be obtained from such basic data.footnote

  7.1.5 footnote The Administration may allow the inclining test of an individual ship or class of ships especially designed for the carriage of liquids or ore in bulk to be dispensed with when reference to existing data for similar ships clearly indicates that due to the ship's proportions and arrangements more than sufficient metacentric height will be available in all probable loading conditions. footnote

  7.1.6 The inclining test prescribed is adaptable for ships with a length below 24 m if special precautions are taken to ensure the accuracy of the test procedure.
