In unmanned machinery spaces suitable warning devices shall be installed to indicate leakage of water into the space or leakage from any other system. 3 In every such vessel valves and other fittings attached to the hull shall be of steel, bronze or other ductile material and pipes between the hull opening and the valve shall be of steel except that in positions elsewhere and in vessels constructed of materials other than steel, other materials may be used provided that they are suitable for their intended service. Heights of hatchway coamings, doorways sills, ventilators and air pipes 13 1 Subject to paragraph (2) of this Rule, in every vessel of 12 metres in length and over to which these Rules apply every hatchway on the freeboard deck shall have a coaming of substantial construction and the height of the coaming above the deck shall be not less than:— a 300 millimetres for vessels with Vessel Numerals up to and including 200; b 380 millimetres for vessels with Vessel Numerals above 200 but no more than 315; c 460 millimetres for vessels with Vessel Numerals above 315 but not more than 1400; d 600 millimetres for vessels with Vessel Numerals above 1400. On superstructure decks the height of the coamings shall be not less than 300 millimetres. 2 In any such vessel the height of hatch coamings specified in paragraph (1) above may be reduced, or the coamings omitted, where compliance with the requirements of paragraph (1) above is not reasonably practicable provided watertight hatch covers are fitted. Such covers shall be kept as small as reasonably practicable, be permanently attached by hinges or equivalent means and capable of being rapidly closed and battened down. 3 In every such vessel the height of sills above the level of the deck in doorways provided in companionways, superstructures, deckhouses and machinery casings which give access to parts of the deck exposed to the weather and sea from spaces below the freeboard deck shall be not less than those specified for hatchway coamings in paragraph (1) above provided that the height of such sills above deck may be reduced where there is no direct access to spaces leading below the freeboard deck and where the deckhouse, superstructures or companionways on the freeboard deck are sub-divided internally. 4 In every such vessel the lowest point at which water might gain access through the air pipes shall be not less than 760 millimetres above the freeboard deck or not less than 450 millimetres above the superstructure deck, provided that these heights may be reduced where compliance with the requirements of this paragraph of these Rules is not reasonably practicable because of interference with fishing operations and provided adequate closing arrangements are fitted. 5 On the freeboard deck of every such vessel the height above deck of ventilators, other than machinery space ventilators, shall be not less than 900 millimetres and on superstructure decks not less than 760 millimetres. The height of ventilators of machinery spaces shall be as high as is reasonable and practicable. 6 In every such vessel the requirements of the preceding paragraphs of this Rule shall apply in relation to the heights of coamings, sills, air pipes and ventilators above an enclosed deck where water may accumulate and present a hazard to the vessel as they apply in relation to the heights of coamings, sills, air pipes and ventilators above the freeboard deck or superstructure deck as the case may be. Freeing ports 14 1 In every vessel of 12 metres in length and over to which these Rules apply where bulwarks on weather parts of the freeboard deck form wells, the minimum freeing port area in square metres (in this Rule referred to as “A”) on each side of the vessel for each well on the freeboard deck shall be determined in accordance with the following formula in relation to the length and height of the bulwark in the well (in this Rule referred to as “l” and “h” respectively) as follows: A = ( 1·0 + 3·5 ⁢ h ) ⁢ l × h 100 l = length of the bulwark in metres. h = mean height of the bulwark in metres. Where side houses of superstructures fitted within the well contribute positive buoyancy to the vessel. A may be reduced except that, where such side houses or superstructures are discontinuous and provide pockets for the accumulation of water, no reduction shall be made. 2 In any such vessel if the well is on a deck whose minimum height at side above the deepest operational waterline is equal to or greater than “R” metres, A may be multiplied by the factor “f” where:— f = 1 - 0·5 ⁢ ( H - R ) ( 2·35 - R ) R = 0·95 ⁢ + ( L - 30 ) ⁢ 0·9 ( ·95 ) H = minimum height in metres measured from the deepest operational waterline to the lowest part of the deck at side upon which the well is formed. L = registered length in metres. In no case shall the factor “f” be less than 0·75. 3 In any such vessel, A may include— a the area of those freeing ports with attached means of closing provided that the freeing ports shall only be closed during fishing operations; and b in stern trawlers the apertures in and under the stern doors. 4 In every such vessel freeing ports shall be so arranged throughout the length of the bulwarks as to provide an effective means of freeing the deck of water. Lower edges of freeing ports shall be as near to the deck as is practicable. Freeing ports greater than 230 millimetres in depth shall be fitted with bars spaced not more than 230 millimetres apart or by other equivalent arrangements. 5 In every such vessel the arrangements provided in the well for the stowage of equipment and the catch shall not impair the effectiveness of the freeing ports. 6 In every such vessel intended to operate in zones where icing occurs the means of closing freeing ports when fitted shall be capable of being readily removed. C FREEBOARD AND STABILITY Freeboard 15 1 Every vessel of 12 metres in length and over to which these Rules apply shall be so designed, constructed and operated as to ensure that in all foreseeable operating conditions the freeboard will be adequate to provide:— a compliance with the stability criteria set out in Rule 16 of these Rules; b reasonable safety for men working on deck; c reasonable safety to the vessel from the entry of water into enclosed spaces having regard to the closing appliances fitted. 2 On each side of every such vessel, draught water marks complying with the requirements of section 7 of the Merchant Shipping Act 1894 as amended by the Merchant Shipping (Metrication) Regulations 1973 shall be provided. Stability 16 Every vessel of 12 metres in length and over to which these Rules apply shall in all operating conditions and circumstances set out in paragraphs 10 and 11 of Schedule 3 to these Rules and in all foreseeable operating conditions satisfy the following stability criteria after due correction for the free surface effects of liquids in tanks:— a the area under the curve of righting levers (GZ curve) shall not be less than:— i 0.055 metre-radians up to an angle of 30 degrees; ii 0.090 metre-radians up to an angle of 40 degrees or such lesser angle of heel at which the lower edges of any openings in the hull, superstructures, deckhouses or companionways, being openings which cannot be closed weathertight, are immersed; iii 0.030 metre-radians between the angles of heel of 30 degrees and 40 degrees or such lesser angle as defined in (ii) above; b the righting lever (GZ) shall be at least 0.20 metres at an angle of heel equal to or greater than 30 degrees; c the maximum righting lever (GZ) shall occur at an angle of heel not less than 25 degrees; d in the upright position the transverse metacentric height (GM) shall not be less than 0.35 metres; provided that, for vessels engaged on single or twin boom fishing the values of dynamic stability, righting lever and metacentric height given in sub-paragraphs (a), (b) and (d) respectively of this Rule shall be increased by 20%.

PART IV EXCEPTIONAL PROVISIONS Exceptional provisions 122 Where these Rules require that the hull or machinery of a vessel shall be constructed in a particular manner or that any particular equipment, fitting, material, appliance or apparatus shall be provided or that particular provisions shall be made, the hull or machinery of the vessel may be constructed in any other manner or any other equipment, fitting, material appliance or apparatus may be provided or other provision made which is at least as effective as that required by these Rules. PART V SURVEYS AND CERTIFICATES Surveys and periodical inspections 123 Every vessel of 12 metres in length and over to which these Rules apply shall be surveyed and periodically inspected in accordance with the requirements of this Part of these Rules.
