Table. 



251 



Column A gives the maximum permissible values of the factor of subdivision for the 

 length of vessels given in Columns B and C. 



Column B is applicable to vessels engaged in mixed cargo and passenger service. 



Column C is applicable to vessels primarily engaged in the transportation of passen- 

 gers. 



(4) For a given length, the value of the factor of subdivision appropriate to a vessel 

 between the two extreme limits will be between the values of the factors determined by 

 the two curves before mentioned, and will be automatically fixed by a "criterion of serv- 

 ice" which is to form the subject of further study. 



Article IX. 



(1) When the factor of subdivision is equal to or less than .5, it may be doubled in 

 order to give at any point of the vessel's length the total length of two adjacent compart- 

 ments; but, in that case, the length of the shorter compartment of any pair shall not be less 

 than one-quarter of the total length so obtained. If one of the two adjacent compartments 

 is situated inside the machinery space and the second is situated outside the machinery 

 space, and the average permeability of the portion of the ship in which the second is situ- 

 ated differs from 80 per cent, the length of the pair of compartments shall be adjusted to 

 the proper value by applying a suitable correction. 



(2) In no case whatever shall the length of any watertight compartment exceed 28 

 meters (equivalent to 92 feet). 



(3) When the factor of subdivision applicable to any vessel is less than .84, but more 

 than .5, the combined length of the two foremost compartments shall not exceed the flood- 

 able length at the extreme forward end, provided also that the length of the second com- 

 partment is not greater than that permissible by Article VIII above, and not less than 3 

 meters (equivalent to 10 feet). 



(4) When the length of the vessel is more than 213 meters (equivalent to 699 feet) 

 but less than 251 meters (equivalent to 823 feet) the floodable length at the forward end 

 of the vessel shall be at least 20 per cent of the vessel's length; and the vessel, forward of 

 a bulkhead placed either at the distance of the actual floodable length abaft the stem or not 

 nearer to the stem than 20 per cent of the vessel's length, shall be divided into at least three 

 compartments.
