Each buoyant rescue quoit shall be attached to not less than 30 m of buoyant line. [The weight of the quoit shall be sufficient to allow it to be thrown the full length of the attached line.] The line should be [8-6 mm] in diameter. [Consider thickness and strength of line; throwability? Consider characteristics of quoit?Get some samples to test.]

The instructions for immediate action shall be waterproof, and shall contain the information required by IMO Resolution A.657(16). [In addition, they shall explain the noise accompanying the venting of the pressure relief valves, and the need to seal them after they have completed venting.] The instruction card shall be located so that it can be easily seen upon entering the liferaft.

4.2118.1 The jack-knife shall be of a single-bladed type fitted with a tin opener, and a shackle to which a lanyard is attached. The jack-knife may optionally be fitted with a tin-opener blade in addition to the cutting blade. The handle shall be approximately 95 mm long. All materials used in the construction of the knife shall be suitable for corrosion resistant in the marine environment, and the blades shall be heat treated to suitable hardness.

　

4.2118.2 The knife blade shall be not less than 2.4 mm thick at the tang, and shall have a triangular section and sheep's foot point. The blade shall have a cutting edge approximately 80 mm in length, and shall have a height of approximately 20 mm at the point. The blade shall be uniformly ground and finished on both sides, and sharpened to a uniform and keen edge, and shall have a common nail nick on one side.

　

4.2118.3 The tin-opener blade, if fitted, shall be not less than 1.8 mm thick at the tang, and 42 to 49 mm long overall. It shall be mounted on the same end of the handle as the knife blade, and in such a manner that both rectangular and circular tins may be opened with a minimum of effort when the knife is held in the right hand and operated in a clockwise direction around the tin. It shall be formed to obtain a smooth cutting action, and designed so that the cutting action turns the ragged cut edge down into the tin. It shall have a common nail nick on one side, and the extreme distal edge shall be pointed.

　

4.2118.4 After cutting various non-metallic objects, including at least 10 shavings from a strip of oak or other hardwood, and if fitted with a tin-opener blade, to open various rectangular and circular cans, the knife shall show no noticeable loss in cutting ability.

　

4.2219.1 The knife shall be of the buoyant non-folding type, with the buoyancy provided by a buoyant handle of suitable buoyant material. The knife in an inflated or rigid/inflated rescue boat, or inflatable liferaft, shall have a rounded point, or otherwise be designed to minimize the possibility of damage to the inflatable chambers. The knife blade shall be of material suitable for the marine environment, heat treated to suitable hardness, and of sufficient strength and sharpness to enable it to cut a typical painter line.

　

4.2219.2 The knife for a rigid liferaft shall be secured to the liferaft by a lanyard, and stowed in a pocket on the exterior of the canopy near the point where the painter is attached to the liferaft. The lanyard shall be long enough to permit the knife to be used to cut the painter.

　

　

4.2320.1 The boarding ladder for a lifeboat shall be capable of being used on either side of the boat to enable persons in the water to board the boat. A boarding ladder for a rigid liferaft is used at any entrance not fitted with a boarding ramp.

　

4.2320.2 The ladder shall be a permanently installed rigid type, or a flexible ladder kept rigged ready for use. A flexible ladder may be kept rigged over the side, so that it is immediately ready for use. The lowest step of the ladder shall be at least 0.4 m below the light waterline of the lifeboat or liferaft. An acceptable configuration for the ladder is as follows:

　

a) The ladder should have flat steps with handhold openings in them;

　

b) Each step should have a bare wood surface, or a non-skid surface;

　

c) The steps of the ladder should be spaced approximately 0.3 m apart; and

　

d) Each suspension member should be at least 15 mm diameter manila rope, or another material provided it is at least 15 mm in diameter and has a breaking strength of at least 17.6 kN. Synthetic rope should not be used unless it is ultraviolet light resistant, or is pigmented in a dark color.

　

　

　

4.24.1 A lifeline shall be buoyant, and becketed around the outside of the lifeboat above the waterline and within reach of a person in the water. Handholds shall have a suitable surface, and be shaped and positioned so as to be easily usable by a person in the water.

　

4.2522.1 The interior lighting system of a partially or totally enclosed lifeboat, or a rigid or inflatable liferaft, shall be of an approved type which has been evaluated for suitability as installed in the survival craftcapable of continuous operation for a period of at least 12 h. It shall be provided with a means to light automatically when a liferaft canopy is erected, and be of sufficient intensity to permit reading of survival and equipment instructions, [when tested in accordance with XXXXX].
