13.2.5.1 One approved immersion suit should be
provided for each person onboard. Due consideration should be given
to the provision of appropriate immersion/thermal protection for children
carried on board; these should be of the insulated type.
However, on application to the Administration, the non-insulated
type may be acceptable for Short Range Yachts dependant on the area
of operation.
However, these need not be provided if the
vessel is operating in water of surface temperatures of 20°C or
more.
