RULES FOR THE DETERMINATION OF THE FREE.
BOARD OF SHELTER-DECKED STEAMERS. By the term “shelter-decked steamer" is meant, for the purpose of the following instructions, a steam vessel having a complete suprestructure of a substantial character extending over the whole length of the vessel, the superstructure deck (hereinafter called the shelter-deck) being continuous and unbroke at the sides of the vessel, but having one or more openings at the middle line, which have 20 permanent means of closing them, but which may or may not have means for temporarily closing them.
In assigning freeboards to shelter-decked vessels, the following rules should be observed :
(1) In making the sheer correction in accordance with para. 16 of the lond line tables, the sheer is to be measured at the ends of the vessel, and the freeboard corrected for sheer in estimating the allowance for erections. (2) (a) In the case of shelter-decked vessels having only one
opening in the shelter deck, the length correction under para. 9 of the load line tables is to be one half that specified in Table A; and the allowance for deck erections is to be determined under para. II in the manner specified below, provided that the effective length of the deck erections, when assessed on the as. sumption that the opening in the deck is an open well, and in accordance with the different regulations contained in the load line tables affecting poops, bridges, and forecastles, open or closed, is not less than ths of the
length of the vessel. (6) In the case of shelter-decked vessels having an opening at
each end of the vessel, and also in the case of vessels having more than two openings in the shelter-deck, the entire correction for length is to be applied, and the allowance for deck erections is to be determined under
para. 12 of the tables. (3) The effective length of the deck erections is to be calculated in the following manner, provided the openings in the shelter-deck do not exceed half the vessel's breadth at the middle of the length of the opening. The length to be taken in the first instance as if each opening were an open well, the value of each part being assessed on that assumption in accordance with the different regulations contained in the load line tables affecting poops, bridge houses, and forecastles, open or closed, and also in accordance with the regulations regarding bridge houses not covering the engine and boiler space. The final allowance for erections will depend upon whether or not temporary but efficient means are provided for closing the openings in the shelter-deck. (a) If efficient means as specified below are provided for tem
porarily closing the openings in the shelter-deck, the effective length of the deck erections is to be reckoned as the length computed as prescribed above, plus half the difference between that length and the length of the vessel,
(6) If efficient means for temporarily closing the openings are not
provided, the effective length of the erections is to be computed by adding to the length computed as above one fourth, instead of one half, the difference between that length
and the length of the vessel. (-) If the openings in the shelter-deck are wider than as specifieil
above, the addition to the assumed length of erections is to be modified in proportion to the relation which the actual opening holds to the specified breadth and to a complete
well. (4) Means for temporarily closing the openings in the shelterdeck may be regarded as efficient if they are at least equivalent to the following in strength and security. The portable planks for closing the openings to be not less in thickness than required by para. 43 of Lloyd's Rule; (1885) for the flat of awning-decks. The planks to be supported by portable beams, fitted either longi. tudlinally or athwartships, spaced not wider than 5 fr. apart, and efficiently secured at their erdi, and the deck in way of the openings to be efficiently supported by pillars from the deck below. The por able planks to be provided with eye bolts and lashings, or some other equally efficient means of securing them in place.
(5) If efficient means are provided for temporarily closing the openings in the shelter-deck in heavy weather, the freeing ports required by para. 11 (f) need not be provided. If, however, efficient means for closing the openings are not provided, whether in vessels with one or with more than one opening in the shelterdeck, then freeing ports with shutiers properly hung are to be fitted, having a minimum area as follows:
If the freeing port area is less than that stated above, an addition is to be made to the freeboard of } per cent. of the vessel's moulded depth, provided, however, that in the case of vessels treated under para. 12, the freeboard is not to be increased beyond that due to deck erections of the same length and character, but with open wells, as determined by the different regulations contained in the load line tables affecting poops, bridge houses, and forecastles.
(6) Shelter.decked vessels having a plating number not exceeding 27,000, and having one opening in the shelter-deck either at the forward or after end of the vessel, and having at least Tooths of the length covered with completely and permanently enclosed deck erections, the bulkhead enclosing the midship part of the erection having no openings in it and being at least oths of the vessel's length from amidships, and having also extra strength as required by Section 44 of Lloyd's Rules for 1889, may be granted the allowance prescribed in para. II, p. 65 of the load line tables for strong well-decked vessels; but in that case in computing the allowance for deck erections, the actual length of the enclosed erections is to be taken as for a well-deckedi vessel without any addition.
(7) The deduction for summer to be intermediate between Tables A. and C., in proportion to the effective length of erections finally allowed for freeboard purposes, and the freeboards assi ned to these vessels must never be less than would be assigned for a complete awning-decked vessel of the same dimensions.
(8) For the purpose of the assignment of freeboards, a hatch way having strong iron or steel coamings, with hatch rest bars of the usual description, and also cleats for bittening down bars securely riveted to the coamings, thwartship beams and fore and afters, substantial hatch covers and tarpaulins, shall be considered to have “permanent means of closing.' And a deck erection having no openings in it, except so protected, shall be held to be “perman. enily enclosed" within the meaning of clause 6 of these rules,
REGULATIONS DATED JANUARY 12TH, 1899, MADE BY THE BOARD
OF TRADE UNDER THE MERCHANT SHIPPING ACT, 1894.
(Vide Orier in Council, January 12th, 1899.)
