After a passenger ship is completely constructed, she shall receive the inclining experiment under the supervision of the shipping authority or ship register institute. The information data relating to the results of the experiment and the calculations of stability shall be submitted for examination and approval by the shipping administration authority or ship register institute.

The information of stability approved by the shipping administration authority or ship register institute mentioned in the preceding article shall be kept onboard the ship for use.

In case of modification of a passenger ship that may substantially affect the stability, the ship shall undergo the inclining experiment once again. In addition, the revised information shall be sent to the shipping administration authority or ship register institute for approval.

If a passenger ship's basic stability information is obtained from another same type ship's inclining experiment results that have been confirmed by the shipping administration authority or ship register institute to be reliably applicable to the ship, she may be exempted from undergoing the inclining experiment pursuant to Article 40 according to the application of the shipowner.

The minimum height of metacentric height aweather required for a passenger ship according to the weather conditions of navigating areas and drafts shall be computed according to the equation specified in Attachment 3.

• Attachment 3.pdf

The min. metacentric height required for a passenger ship when it carries passengers shall be computed according to the equation specified in Attachment 4.

• Attachment 4.pdf

The intact stability of a passenger ship shall be computed according to the weather conditions in the navigation area and the carriage of passengers and considering the free surface effect of normally, non-fully filled liquid tank under any normal carriage condition. The standard shall be one of the net metacentric heights as specified in the two preceding articles; whichever is the greater.

The stability of a damaged passenger ship shall comply with the provisions for the subdivision of passenger ships set forth in relevant laws and regulations.

In case of a passenger ship of special proportion and type, to which the provisions set forth in Articles 44 to 46 do not apply, the calculations of its stability shall be otherwise submitted to the shipping administration authority or ship register institute for approval.

The ballast for a passenger ship with a length of less than 24 meters needed to comply with stability specifications shall be the permanent ballast.
