SAFETY OF LIFE AT SEA C159 



Provided that in the case of ships loaded with bulk giain other than 

 linseed in which a metacentric height (after correction for the free surface 

 effects of liquids in tanks) is maintained throughout the voyage of not less 

 than 12 inches (or 031 metres) in the case of one or two deck ships and not 

 less than 14 inches (or 36 metres) in the case of other ships, longitudinal 

 bulkheads or shifting boards need not be fitted: — 



(a) below and within 7 feet (or 2- 13 metres) of a feeder, but only in way 



of a hatchway, if that feeder contains, or all the feeders collectively 

 feeding a compartment contain, not less than 5 per cent, of the 

 quantity of grain carried in the compartment which is fed; 



(b) in feeders which meet the requirements of paragraph {a) of this 



Regulation and which have such dimensions that the free grain 

 surface will remain within the feeders throughout the voyage after 

 allowing for a sinkage of grain amounting to 2 per cent, of the 

 volume of the compartment fed and a shift of the free grain 

 surface to an angle of 12 degrees to the horizontal; in this case 

 the possible effects of the above mentioned movement of the free 

 grain surfaces within the feeders shall be taken into account in 

 calculating the metacentric height given above; 



(c) in way of the hatchway where the bulk grain beneath the hatchway 

 is trimmed in the form of a saucer hard up to the deckhead beyond 

 the hatchway and is topped off with bagged grain or other suitable 

 bagged cargo extending to a height in the centre of the saucer 

 of not less than 6 feet (or 1 • 83 metres) above the top of the bulk 

 grain (measured below the deck line); the bagged grain or other 

 suitable bagged cargo shall fill the hatchway and the saucer below 

 and shall be stowed tightly against the deckhead, the longitudinal 

 bulkheads, the hatchway beams and the hatchway side and end 

 coamings. 



Regulation 5 



Stowage of partly filled holds and compartments 



Subject to the provisions of Regulation 6 of this Chapter, if any hold 

 or compartment is partly filled with bulk grain: — 



{a) it shall be di\ided by a longitudinal bulkhead or shifting boards, in 

 line with, or not more than 5 per cent, of the moulded breadth of 

 the ship from, the centre line or by longitudinal bulkheads or 

 shifting boards off the centre line of the ship provided that the 

 distance between them shall not exceed 60 per cent, of the moulded 

 breadth of the ship. In every case the longitudinal bulkheads 

 or shifting boards shall be properly constructed and shall extend 

 from the bottom of the hold or deck, as the case may be, to a 

 height of not less than 2 feet (or 61 metres) above the surface 

 of the bulk grain. 



Provided that, except in the case of holds partly filled with 

 linseed in bulk, longitudinal bulkheads or shiftmg boards need not
