NEW CLASS B, C AND D AND EXISTING CLASS B SHIPS:

Every passenger ship shall be inclined upon its completion and the elements of its stability determined. The master shall be supplied with such information, approved by the Administration of the flag State, as is necessary to enable him by rapid and simple processes to obtain accurate guidance as to the stability of the ship under varying conditions of service. Where any alterations are made to a ship so as to affect materially the stability information supplied to the master, amended stability information shall be provided. If necessary the ship shall be re-inclined. At periodical intervals not exceeding five years, a lightweight survey shall be carried out to verify any changes in the light ship displacement and longitudinal centre of gravity. The ship shall 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 the length of the ship is found or anticipated. The Administration of the flag State may allow the inclining test of an individual ship 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 of the flag State that reliable stability information for the exempted ship can be obtained from such basic data.
