Retro-reflective materials should be fitted around the
canopy of the liferaft. The material should be sufficiently wide and
long to give a minimum area of 150cm2 and should be spaced
at suitable intervals (approximately 80cm from centre to centre) at
a suitable height above the waterline, doorways included, if suitable.
On inflatable liferafts, retro-reflective materials should also be
fitted to the underside of the floor, cross-shaped in the centre.
The dimension of the cross to be half the diameter of the liferaft,
and a similar cross should be applied to the top of the canopy.
On liferafts which are not equipped with canopies, materials
which should be sufficiently wide and long to give a minimum area
of 150 cm2 should be attached to each buoyancy chamber
at suitable intervals (approximately 80cm centre to centre) in such
a manner that they are visible both from the air and from a ship.
