4.1.3.1 Lifelines shall be securely becketed around
the inside and outside of the liferaft.
4.1.3.2 The liferaft shall be fitted with an efficient
painter or length equal to not less than 10 m plus the distance from
the stowed position to the waterline in the lightest seagoing condition
or 15 m whichever is the greater. The breaking strength of the painter
system, including its means of attachment to the liferaft, except
the weak link required by paragraph 4.1.6, shall be not less than
15.0 kN for liferafts permitted to accommodate more than 25 persons,
not less than 10.0 kN for liferafts permitted to accommodate 9 to
25 persons and not less than 7.5 kN for any other liferaft.
4.1.3.3 A manually controlled exterior light shall
be fitted to the uppermost portion of the liferaft canopy or structure.
The light shall be white and be capable of operating continuously
for at least 12 h with a luminous intensity of not less than 4.3 cd
in all directions of the upper hemisphere. However, if the light is
a flashing light it shall flash at a rate of not less than 50 flashes
and not more than 70 flashes per min for the 12 h operating period
with an equivalent effective luminous intensity. The lamp shall light
automatically when the canopy is erected. Batteries shall be of a
type that does not deteriorate due to dampness or humidity in the
stowed liferaft.
4.1.3.4 A manually controlled interior light shall
be fitted inside the liferaft capable of continuous operation for
a period of at least 12 h. It shall light automatically when the canopy
is erected and shall produce an arithmetic mean luminous intensity
of not less than 0.5 cd when measured over the entire upper hemisphere
to permit reading of survival and equipment instructions. Batteries
shall be of a type that does not deteriorate due to damp or humidity
in the stowed liferaft.
