Rule—2. Stowage of Full Compartments.
(1) Except as hereinafter provided, any compartment which is entirely filled with bulk grain shall be divided either
(a) 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
(b) by longitudinal bulkheads or shifting boards off the centre line of the ship provided that the distance between them does not exceed 60 per cent of the moulded breadth of the ship and trimming hatches of suitable size, suitably placed are provided in the wings at longitudinal intervals of not more than 25 feet with end trimming hatches placed not more than 12 feet from transverse bulkheads.
(2) In every case, the longitudinal bulkheads or shifting boards shall be properly constructed and fitted grain tight with proper fittings between the beams and shall extend to the top of the feeders of the hold or compartment in which they are situated.
(3) In the holds, the longitudinal bulkheads or shifting boards shall extend downwards from the underside of the deck to a distance of at least one-third the depth of the hold or 8 feet, whichever is greater. In other compartments such as in 'tween decks, such longitudinal bulkheads or shifting boards shall extend from deck to deck.
(4) The provisions of sub-rules (1), (2) and (3) of this rule shall not apply to
(a) a compartment other than a hold if bagged grain or other suitable cargo therein is tightly stowed in the wings to a width, at any point, of not less than 20 per cent of the corresponding breadth of the ship;
(b) parts of compartments where the maximum breadth of the deck head within such parts does not exceed one-half of the moulded breadth of the ship;
(c) except in the case of compartments loaded with bulk linseed, those parts of a compartment which, in ships which maintain throughout the voyage a metacentric height of not less than 12 inches in the case of single deck or two deck ships and not less than 14 inches in the case of other ships, are:
(i) below and within 7 feet of a feeder, but only below or abreast 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;
(ii) below or abreast of a hatchway where the bulk grain beneath the hatchway is trimmed in the form of a saucer hard up to the deck head beyond the hatchway to a depth in the centre of the saucer of not less than 6 feet measured below the deck line and is topped off with bagged grain or other suitable bagged cargo so as to fill the hatchway and the saucer below and is stowed tightly against the deck head, the longitudinal bulkheads, the hatchway beams and the hatchway side and end coamings.
