Part I - General

4.1 Strength of Ship and Subdivision - General

(1) The Administration shall satisfy itself that the general structural strength of the ship is adequate for the draft corresponding to the freeboard assigned.

(2) The ship shall in any case be constructed in accordance with the requirements of Chapter 3 (Load Lines) and it shall comply with the Intact Stability Code 2008 or with intact stability standards acceptable to the Administration.

(3) Ships shall be as efficiently subdivided as is possible having regard to the nature of the service for which they are intended and the degree of subdivision shall vary with the subdivision length (Ls) of the ship and with the service, in such manner that the highest degree of subdivision corresponds with the ships of greatest subdivision length (Ls), primarily engaged in the carriage of passengers.

(4) Where it is proposed to fit decks, inner skins or longitudinal bulkheads of sufficient tightness to seriously restrict the flow of water, the Administration shall be satisfied that proper consideration is given to beneficial or adverse effects of such structures in the calculations.

(5) The Table in Annex 1 summarises the stability provisions applicable to the various categories of Passenger Yacht.
