having friends who have just a completed sea survival course down here in Oz I was absolutely flabergasted when I was told the following story. I had three different friends do their respective sea safety course at 3 different teaching facilities in two different states. Part of the course was to do a simulated abandon ship. All participants were wearing manuel or self inflating life jackets. On every course some of these life jackets failed to inflate. What was amazing is that in one class of 15 people, seven of the life jackets failed to inflate. Now while you are training this is not so bad but what happens in a real life drama when you are out in the middle of the deep blue and the dam thing does not inflate.
All my friends are now going to the PFD with in built flotation, they may be bulkier but at least when you go into the drink its there working already,
Has anyone else had experience in this. It reminds me of the old parachute joke, if it does not open first go just bring it back for a full refund
