Rule 126
Rule 125(2)
Rules 16 and 74
The book to be kept on board the vessel pursuant to Rule 74 of these Rules shall contain the following information:
1. A statement of the vessel's name, port of registry, official number, registration letters, principal dimensions, gross and register tonnages, displacement and minimum freeboard in the deepest foreseeable operating condition shall be included in such information.
2. A profile plan of the vessel drawn to scale showing with their names all compartments, tanks, storerooms, crew accommodation spaces and the position of the mid-point of the length between perpendiculars shall be provided.
3. A tabular statement of the capacity and position of the centre of gravity, longitudinally and vertically of every compartment available for the carriage of cargo, fuel, stores, feed water, domestic water, water ballast, and crew and effects shall be included in such information. The free surface function defined in paragraph 9 below shall also be included for each tank designed to carry liquid. Details of the volumetric-centre of the total internal volume of the fish-hold shall be included in such information. The calculation may take into account the effect of assuming a void space between the top of the catch and the underside of the deckhead provided that under normal operating conditions provision has been made for the effective control of the loading in order to ensure that the actual void space will always be equal to or greater than that assumed in such a calculation.
4. Where deck cargo is carried by a vessel the estimated weight and disposition of deck cargo the vessel may be expected to carry while satisfying the stability criteria set out in Rule 16 of these Rules shall be included in such information.
5. A diagram or tabular statement shall be provided showing for a suitable range of mean draughts and at the trim stated, the following hydrostatic particulars of the vessel:—
(i)the heights of the transverse metacentres;
(ii)moments to change trim one centimetre;
(iii)tonnes per centimetre immersion;
(iv)longitudinal position of the centre of flotation;
(v)vertical and longitudinal positions of the centre of buoyancy;
(vi)displacement in tonnes.
Where vessels have raked keels the same datum shall be used for the hydrostatics as was employed in determining the requirements of paragraph 3 above. In such cases full information shall be included in respect of the rake and dimensions of the keel and may be given in the form of a diagram.
6. A diagram shall be provided showing cross curves of stability indicating the assumed position of the axis from which the righting levers are measured and the trim which has been assumed. Where vessels have raked keels any datum other than a line through the top of the keel amidships shall be clearly defined.
7. The information provided under paragraphs 5 and 6 above shall be at such a nominal trim that represents accurately the vessel in all normal operating trims. Where calculations show that there are significant numerical variations in these operating trims the information provided under paragraphs 5 and 6 above shall be repeated over such a range of trims to allow an accurate interpolation of such information at any normal operating trim.
8. Superstructure deckhouses, companionways located on the freeboard deck, including hatchway structures may be taken into account in deriving such cross-curves of stability provided that their location, integrity and means of closure will effectively contribute to the buoyancy.
9. An example shall be included in such information to show the corrections applied to the transverse metacentric height and righting levers (GZ) for the effects of the free surfaces of liquids in tanks and shall be calculated and taken into account as follows:—
(i)the metacentric height in metres shall be reduced by an amount equal to the total of the free surface functions for each tank divided by the vessel's displacement in tonnes. For each tank the free surface function is given by:—
No math image to display
p = specific gravity of the liquid;
i = transverse moment of inertia of the surface
No math image to display
L = length and B = breadth of the surface of metres);
No math image to display
(ii)the righting lever (GZ) curves shall be corrected by either:—
(a) adding the free surface correction calculated under (i) above to the value in metres of the calculated height of centre of gravity of the vessel above the datum; or
(b) making direct calculations of the heeling moment due to the liquid surface being inclined at the selected angle of heel where such calculations take proper account of the position of liquid surface in relation to the geometric configuration of the tank. The correction to the righting lever (GZ) at any selected angle of heel shall then be the summation of the individual heeling moments of the tanks considered, divided by the vessel's displacement.
10. A stability statement and diagram shall be provided for the usual condition of the vessel:—
(a)in the lightship condition:
the vessel shall be assumed to be empty except for water in boilers and liquid in pipe systems including header tanks. The weight and position of the centre of gravity of any permanent ballast or fishing gear shall be indicated where this is known;
(b)in each of the following circumstances so far as they may be applicable to the vessel in its foreseeable operating conditions:—
(i)on departure from port:
the vessel shall be assumed to be loaded with the necessary equipment, materials and supplies including ice, fuel, stores and water;
(ii)on arrival at fishing grounds:
as sub-paragraph (i) above but account taken of the consumption of fuel and stores:
(iii)on arrival at fishing grounds:
as sub-paragraph (ii) above but the appropriate icing-up allowance as set out in paragraph 14 below shall be taken into account;
(iv)on departure from fishing grounds:
the vessel shall be assumed to be loaded with its maximum catch but account taken of the consumption of fuel and stores;
(v)on departure from fishing grounds:
as sub-paragraph (iv) above but the appropriate icing-up allowance as set out in paragraph 14 below shall be taken into account;
(vi)on departure from fishing grounds:
the vessel shall be assumed to be loaded with 20% of its maximum catch but account taken of the consumption of fuel and stores;
(vii)on departure from fishing grounds:
as sub-paragraph (vi) above, but the appropriate icing-up allowance as set out in paragraph 14 below shall be taken into account;
(viii)on arrival at port with maximum catch:
account shall be taken of the consumption of fuel and stores;
(ix)on arrival at port with 20% maximum catch:
account shall be taken of the consumption of fuel and stores;
(x)if any part of the catch normally remains on deck, further statements and diagrams appertaining to that condition in all the appropriate circumstances set out in sub-paragraphs (iv) to (ix) inclusive shall be provided.
The total free surface correction for the effect of liquid in tanks shall be applied to each loading condition set out in the foregoing provisions of this paragraph. The free surface correction shall take into account the amounts of fuel, lubricating oil, feed and fresh water in the vessel in each such loading condition.
The working instructions placed on board pursuant to Rule 75 shall generally be based upon the conditions specified in this paragraph and shall form part of this stability statement.
11. Where provision is made in a particular area of the vessel for the washing and cleaning of the catch which could lead to an accumulation of loose water a further statement and diagram shall be provided appropriate to that condition which takes into account the adverse effects of such loose water, it being assumed that:—
(i)the amount of loose water on deck is determined by the size and disposition of the retaining devices; and
(ii)in all other respects the vessel is loaded in accordance with (iv) or (vi) of paragraph 10 above, whichever is the less favourable with regard to the vessel's stability.
12. Each stability statement shall consist of:—
(i)a profile drawn to a suitable scale showing the disposition of the deadweight components;

The diagram shall also show the corresponding numerical values of the stability parameters defined in Rule 16 of these Rules.
13. The information provided under sub-paragraph (iii) of paragraph 12 above may be supplemented by a graph or tabular statement showing the maximum permissible deadweight moment over a range of draughts which shall cover foreseeable operating conditions. At any given draught this maximum permissible deadweight moment value is the total vertical moment, about a convenient base line, of all the component weights of the total deadweight which, at that draught, will ensure minimum compliance with the stability criteria requirements of Rule 16 of these Rules. If an allowance for the weight due to icing-up is required this shall be taken into account by a suitable reduction in the permissible moment. Where the stability information is supplied in accordance with the requirements of this paragraph the tabular statement required in accordance with sub-paragraph 12(ii) above shall include the deadweight moment appropriate to each condition and an example shall be added to the stability information to demonstrate the assessment of the stability.
14. The icing-up allowances which represent the added weight due to ice accretion on the exposed surfaces of the hull, superstructure, deck, deckhouses and companionways shall be calculated as follows:—
(i)full icing allowance:
all exposed horizontal surfaces (decks, house tops, etc.) shall be assumed to carry an ice weight of 30 kilogrammes per square metre.
The projected lateral area of the vessel above the waterline (a silhouette) shall be assumed to carry an ice weight of 15 kilogrammes per square metre.
The height of the centre of gravity shall be calculated according to the heights of the respective areas and in the case of the projected lateral area the effect of sundry booms, rails, wires, etc., which will not have been included in the area calculated shall be taken into account by increasing by 5% the weight due to the lateral area and the moment of this weight by 10%. This allowance shall apply in winter (1st November to 30th April inclusive in the northern hemisphere) to vessels which operate in the following areas:—
(a) the area north of latitude 66°30'N. between longitude 10°W. and the Norwegian Coast;
(b)the area north of latitude 63°N. between longitude 28°W. and 10°W.;
(c)the area north of latitude 45°N. between the North American continent and longitude 28°W.;

(e)Bering and Okhotsk seas and Tatar Strait;
(f)South of latitude 60°S.
(ii)Half of the full icing allowance:
this shall be taken as one half of that calculated under sub-paragraph (i) of this paragraph and shall apply in winter to vessels which operate in all areas north of latitude 61°N. between longitude 28°W. and the Norwegian coast and south of the areas defined as the lower limit for the full icing allowance between longitude 28°W. and the Norwegian coast.
15. Information shall be provided in respect of the assumptions made in calculating the condition of the vessel in each of the circumstances set out in paragraph 10 above for the following:—

5. Every lifeboat shall be so constructed that it shall be capable of maintaining positive stability when open to the sea and loaded with its full complement of persons and equipment.
6. Every lifeboat shall be properly constructed for the purpose for which it is intended and shall be of sufficient strength to permit its being safety lowered into the water when loaded with its full complement of persons and equipment. It shall be of such strength that it will not suffer residual deflection if subjected to an overload of at least 25 per cent.
7. No lifeboat shall be less than 4.9 metres in length except that where these Rules permit a lifeboat to be carried as an alternative to a Class C boat, the length of such lifeboat shall not be less than that of the Class C boat as determined in accordance with paragraph 1 of Schedule 8 to these Rules.
8. No lifeboat when laden with its full complement of persons (calculated at 75 kilogrammes per person) and equipment shall weigh more than 20 tonnes.
9. In every lifeboat all thwart and side seats shall be fitted as low in the lifeboat as practicable and bottom boards shall be fitted.
10. Every lifeboat shall have a mean sheer at least equal to 4 per cent of its length. The sheer shall be approximately parabolic in form.

(b)that equal to 10 per cent of the cubic capacity of the lifeboat.
Rule 82(2)
1. Subject to the provisions of paragraph 4 below, the cubic capacity of a lifeboat for the purposes of these Rules shall be measured in cubic metres and shall be determined by Stirling's (Simpson's) Rule, which may be considered as given by the following formula:—
No math image to display
L denotes the length of the lifeboat in metres from the inside of the shell at the top of the stem to the corresponding point at the top of the stern post; in the case of a lifeboat with a square stern the length is measured to the inside of the top of the transom; and
A, B, C, denote respectively the areas of the cross-sections at the quarter length forward, amidships and the quarter length aft which correspond to the three points obtained by dividing L into four equal parts (the areas corresponding to the two ends of the lifeboat shall be considered negligible).
The areas A, B, C shall be deemed to be given in square metres by the successive application of the following formula to each of the three cross-sections:—
No math image to display
h denotes the depth measured in metres inside the shell from the keel to the level of the gunwale, or, in certain cases, to a lower level as determined hereafter; and a, b, c, d, e denote the horizontal breadths of the lifeboat measured in metres inside the shall at the upper and lower points of the depth and at the three points obtained by dividing h into four equal parts (a and e being the breadths at the extreme points, and c at the middle point of h).
The capacity of a square-sterned lifeboat shall be calculated as if the lifeboat had a pointed stern.
2. If the sheer of the gunwale, measured at the two points situated at a quarter of the length of the lifeboat from the ends, exceeds 1 per cent of the length of the lifeboat, the depth employed in calculating the area of the cross-section A or C shall be deemed to be the depth amidships plus 1 per cent of the length of the lifeboat.
3. If the depth of the lifeboat amidships exceeds 45 per cent of the breadth, the depth employed in calculating the area of the amidship cross-section B shall be deemed to be equal to 45 per cent of the breadth, and the depth employed in calculating the areas of the quarter length sections A and C is obtained by increasing this last figure by an amount equal to 1 per cent of the length of the lifeboat:
4. Unless the owner of the lifeboat requires the cubic capacity to be determined by exact measurements, the cubic capacity of a lifeboat constructed of wooden planks may be assumed to be the product of the length, the breadth and the depth multiplied by 0.6 if this formula does not give a greater capacity than that obtained by the formula set out in paragraph 1 above. The dimensions shall be measured in the following manner:—
Length—from the intersection of the outside of the planking with the top of the stem to the corresponding point at the stern post, or in the case of a square-sterned lifeboat, to the after side of the top of the transom;
Breadth—from the outside of the planking at the point where the breadth of the lifeboat is greatest;
Depth—amidships inside the planking from the keel to the level of the top of the gunwale, but the depth used in calculating the cubic capacity may not in any case exceed 45 per cent of the breadth.
5. The cubic capacity of a motor lifeboat or a lifeboat fitted with other propelling gear shall be obtained from the gross capacity by deducting a volume equal to that occupied by the motor and its accessories or the gearbox of the other propelling gear.
Rule 82(5)(a)
1. The engine shall be capable of being readily started in cold weather and of running reliably under conditions of extremes of temperatures.
2. The engine shall operate properly under conditions of at least 10 degrees list and 10 degrees trim. Circulating water pumps where fitted shall be self-priming.
3. The engine and its accessories, including the fuel tank, pipes and fittings, shall be adequately protected to ensure reliable operation under conditions likely to arise at sea during adverse weather. The engine casing shall additionally be fire-resisting and in the case of air-cooled diesel engines shall be so designed that the supply of cooling air is not restricted.
4. Means shall be provided in all lifeboats to prevent the spread of oil. In a wooden lifeboat a metal tray shall be fitted under the engine.
5. The fuel tank shall be substantially constructed, securely fixed in position with a metal tray underneath and fitted with suitable filling, vapour venting and relief arrangements. No part of the tank or its connections nor any part of the fuel piping or fittings shall depend on soft solder for tightness, and tanks made of steel shall be protected externally against corrosion by sea water by metal spraying or similar means. The tanks and its connections shall be capable of withstanding hydraulic pressure corresponding to a head of at least 4·5 metres. A cock shall be fitted at each end of the fuel pipe.
6. The engine and fuel tank spaces shall be efficiently ventilated.
7. The shafting and other moving parts shall be fenced where necessary to protect the persons in the lifeboat from injury.
Rule 83
1. Every Class C boat shall be an open boat constructed with rigid sides.
2. The boat shall be of such form and proportions that it shall have ample stability in a seaway and sufficient freeboard when loaded with its equipment and the number of persons specified in column (3) of paragraph 3 below.
3. The length of the boat and the number of persons for whom seating shall be provided in the boat shall be determined in accordance with the following table:—
(1) | (2) | (3) |
---|---|---|
Number of Persons on board the vessel | Minimum length of boat in metres | Minimum Seating Capacity of boat (persons) |
More than 8 | 4.8 | 9 |
8 | 4.5 | 8 |
6 or 7 | 4.2 | 7 |
5 | 3.9 | 5 |
4 or less | 3.6 | 4 |
4. All thwart and side seats in the boat shall be fitted as low in the boat as practicable and bottom boards shall be fitted.
5. The boat shall be square-sterned and shall have a mean shear at least equal to five per cent of its length.

7. Every boat shall be fitted with internal buoyancy appliances which shall consist either of air cases or buoyant material which shall not be adversely affected by oil or oil products and which shall not adversely affect the boat.
8. The total volume of the internal buoyancy appliances shall be such that it will be at least equal to the sum of the volumes of:
(a)that required to float the boat and its full equipment when the boat is flooded and open to the sea so that the top of the gunwale amidships is not submerged; and
(b)that equal to 7·5 per cent of the cubic capacity of the boat which shall be determined in the same manner as that prescribed for lifeboats in Schedule 5 to these Rules.

In the case of gravity type davits comprising arms mounted on rollers which engage with and travel down fixed inclined trackways, the trackways shall be inclined at an angle of not less than 30 degrees to the horizontal when the vessel is upright:
3. Luffing davits. The operating gear of all luffing type davits shall be of sufficient power to ensure that the lifeboats, Class C boats or other boats fully equipped and manned with the launching crew, but not loaded with other persons, can be turned out against a list of at least 15 degrees.
4. Mechanically controlled single-arm davits. The working load of any mechanically controlled single-arm davit shall not exceed 1·5 tonnes.
5. Stresses.
(a)In the case of davits other than mechanically controlled single-arm davits the designed stress on the davit arms, when operating under maximum load and conditions of trim and of list, shall afford an adequate factor of safety having regard to the quality of the material used, the method of construction and the live nature of the load to which the davits are subjected.
(b)In the case of mechanically controlled single-arm davits the designed stress on the davit when operating under maximum load and conditions of favourable list shall afford an adequate factor of safety having regard to the quality of the material used, the method of construction and the live nature of the load to which the davit is subjected.
6. Static load test. Each davit with its arm at full out-reach shall be capable of withstanding a static load test of not less than 2·2 times that part of the working load supported by the arm.
7. Attachments at the davit head. The attachments at the davit head from which the blocks are suspended shall be capable of withstanding a proof load test of not less than 2½ times the maximum load on the attachments.
8. Blocks.
(a)All blocks used in the operation of hoisting and lowering of lifeboats, Class C boats or other boats shall be of a design that affords an adequate factor of safety. Lower blocks, when fitted, shall be non-toppling and in the case of emergency lifeboats, provision shall be made to prevent the falls from cabling. The size of blocks shall be commensurate with the size of the falls.
(b)A metal block shall be capable of withstanding a proof load test of not less than 2½ times the maximum load it is intended to carry in service.

Component parts of blocks other than their sheaves shall be of ductile material.
(c)A wood block shall be capable of withstanding a proof load of not less than 2½ times the load on the block. The width between the cheeks shall be 10 millimetres greater than the diameter of new cordage ropes when those ropes are 95 millimetres in circumference, and less in proportion to the circumference of the ropes when they are smaller.
9. Wire ropes.
(a)The breaking tensile load of each wire rope used for lowering lifeboats, Class C boats or other boats shall be not less than six times the maximum load on the wire rope when lowering, hoisting or stowing.
(b)Wire ropes shall be securely attached to the drum of the winch, and the end attachment of the wires and other parts from which the lifeboat, Class C boat or other boat is to be suspended shall be capable of withstanding a proof load of not less than 2½ times the load on such attachments and other parts.
(c)Where wire rope splices or ferrule-secured eye terminals are used they shall be capable of withstanding a proof test of not less than 2½ times the load imposed on them in service unless samples representing each size of wire on which they are used show a factor of safety of at least 5 when tested to destruction.
10. Winches.
(a)In the case of davits other than mechanically controlled single-arm davits, winch drums shall be arranged to keep the two falls separate and to enable them to pay out at the same rate. The leads of the wire ropes shall be such that they will wind evenly on the drums and lead blocks shall be arranged to give a fleet angle or angle of lead of not more than five degrees for grooved drums and three degrees for ungrooved drums. In the case of mechanically controlled single-arm davits the lead of the wire rope fall shall be such that the fall winds evenly on the drum.
(b)Winch brakes shall be of robust construction and afford complete control and limitation of speed in the operation of lowering. The hand brake shall be so arranged that it is normally in the “ON” position and returns to the “ON” position when the control handle is not being operated. The weight on the brake lever shall be sufficient to operate the brake effectively without additional pressure. The brake gear shall include means for automatically controlling the speed of lowering to ensure that the lifeboat, Class C boat or other boat is lowered expeditiously without exceeding a rate of lowering consistent with safety. For this purpose, the automatic brake shall be set to give a speed of lowering of the lifeboat of between 18 and 36 metres per minute. Ratchet gear shall be incorporated in the hand brake mechanism of lifeboat winches. Where practicable the brake gear shall be so situated as to enable the man operating the winch to have the lifeboat, Class C boat or other boat under observation during the whole process of its being launched into the water, provided that winches serving emergency lifeboats shall in any case be so placed.

They shall be able to pass freely under any conditions through a hole 10 millimetres larger than the nominal diameter of the rope. The breaking load of each rope used for lowering life-boats, Class C boats or other boats shall be not less than 6 times the maximum load on the rope when lowering or hoisting. Rope of less than 65 millimetres in circumference shall not be used for lifeboat falls. Winding reels or flaking boxes for the manilla rope falls shall be provided.
12. Bollards. Suitable bollards or other equally effective appliances for lowering any lifeboat, Class C boat or other boat shall be provided in all cases where cordage rope falls are used. Such bollards or other appliances shall be sited so as to ensure that the lifeboat, Class C boat or other boat served by them can be safely lowered, and fairleads or lead sheaves shall be fitted so as to ensure that it shall not be lifted during the process of turning out or swinging out.
1. General, Tests shall be made to ensure that all lifeboats, Class C boats or other boats attached to davits can be re-stowed from the embarkation position safely and with facility when loaded with the required equipment and that when so loaded the lifeboat, Class C boat or other boat can, when released, be lowered by gravity into the water against the frictional resistance of the winch, falls, blocks and other associated gear.
