someone mentioned earlier that his lifejacket had a bit of difficulty parting the velcro on one sidewhen inflating-which brings me on to an incident a couple of years back on the course we run every year for a group of local authority beachguards. As part of their training their boss wants them to inflate at least one manual lifejacket a year in the water so they can see what happens and to make sure they know which bit to pull !
Now James thought he would give his jacket a head start and opened the outer cover velcros and entered the water with the jacket opened flat but not inflated. When he pulled the cord nothing happened no matter how hard he tried. His colleagues though it hilarious and suggested tht he should not take up skydiving! When we examined the jacket it was obvious why - the cover panel inside the jacket is a very loose fitting thing and all that was happening was that the bottle assembly was moving around as he pulled the cord. Folded the jacket up again so that it holds the botle secure and it went off perfectlly when he pulled the string. So the moral is I suppose if you know you are going to end up in the water don't open the covering in an attempt to help it -& - if at first you don't succeed then sky diving is not for you
