(0 The total weight of the liferaft, its valise or other container and its 

 equipment shall not exceed 400 lb. (or 180 kilogrammes). 



0") The number of persons which an inflatable liferaft shall be permitted 

 to accommodate shall be equal to : — 



(i) the greatest whole number obtained by dividing by 3-4 the volume, 

 measured in cubic feet (or by 96 the volume, measured in cubic 

 decimetres) of the main buoyancy tubes (which for this purpose 

 shall include neither the arches nor the thwart or thwarts if fitted) 

 when inflated, or 



(ii) the greatest whole number obtained by dividing by 4 the area, 

 measured in square feet (or by 3,720 the area measured in square 

 centimetres) of the floor (which for this purpose may include the 

 thwart or thwarts if fitted) of the liferaft when inflated whichever 

 number shall be the less. 



(k) The floor of the liferaft shall be waterproof and shall be capable of 

 being sufficiently insulated against cold 



(/) The liferaft shall be inflated by a gas which is not injurious to the 

 occupants and the inflation shall take place automatically either on the 

 pulling of a line or by some other equally simple and efficient method. Means 

 shall be provided whereby the topping-up pump or bellows required by 

 Regulation 17 of this Chapter may be used to maintain pressure. 



(m) The liferaft shall be of approved material and construction, and shall 

 be so constructed as to be capable of withstanding exposure for 30 days 

 afloat in all sea conditions. 



(n) No liferaft shall be approved which has a carrying capacity calculated 

 in accordance with paragraph 0) of this Regulation of less than six persons. 

 The maximum number of persons calculated in accordance with that 

 paragraph for which an inflatable liferaft may be approved shall be at the 

 discretion of the Administration, but shall in no case exceed 25. 



(o) The liferaft shall be capable of operating throughout a temperature 

 range of 150°F. to minus 22°F. (or 66X. to minus 30°C.). 



(p) The liferaft shall be so stowed as to be readily available in case of 

 emergency. 



iq) The liferaft shall be fitted with arrangements enabling it to be readily 

 towed. 



Regulation 16 



Requirements for Rigid Liferaft s 



(a) Every rigid liferaft shall be so constructed that if it is dropped into 

 the water from its stowed position neither the liferaft nor its equipment will 

 be damaged.
