Not really,was sent on the course along with others in'61.Consisted of all aspects and maintainence of the survival inflatable life rafts.
Generally one to a ship and two to a carrier.
Inspected and maintained the rafts,taught others by jumping in the oggin with the raft upside down,turning into wind then standing the gas bottles to topple the raft upright[pretty hard to do].Checked all the contents,revelled in the fact if the ship went down we were the only people who could tell the skipper what to do!Supposedly!
Emphasised the 3 P's cut the painter,have a piss[bladder swells up in those rafts making it hard to pass water]take seasick pills.
Could go on about what fish to avoid but you get the drift.
It was a 10 day course for me and quite involved not a job for the boys.
I was picked[AB] because my draft was for a NILE trained seaman.
All ships had to have NILE men on board or they could not sail.
Did a full inspection of rafts once a month and inflated one once very three months.Repacking was a sod so we kept spares and sent them back to makers Frankestein of Liverpool!
