Agreed

But It didnt need a good soaking to get my XM one to go off ... on a nice dry day too .. inside its sell by date aswell .. still... it adds that extra... 'je ne sais quoi' for the skipper,.. when already concerned with other on board safety matters

I wear a manual inflate as I am usually driving a safety Boat and in the worst case may need to be able to jump in to help get somebody out from under a boat. One thing I hadn't realised when I set it off one day, was that you really need it to be fairly loose on your torso. When mine inflated, it nearly crushed my ribs!

The life jacket should be as tight you can get a fist in between the straps - I will post link later once back near a computer!

Having used most types of jackets we just use the crew saver foam & air ones for the sib less hassle for what we want nowadays.

Bouyancy aid for normal use then for the extra lifejacket mode it can be inflated by mouth ,

Even just using the foam only mode classing it as a B/A it will turn us over from face down within a few moments especially if there's a bit of wave motion ,
It's not a bad idea getting used to your lifejacket it can be a bit daunting if its the first time you hang from the straps in deep water & even more daunting if there's no crutch strap fitted .

I try encourage my young lad to have a float about with his on in the water just about every time we have a run out ,
at least he is now aware of how importantly it is wearing it correctly and not just taking it for granted .

Yeah that is what mine were and had no problems. Maybe I was just lucky!

Not all hammar bottles are contained within the bladder Mine aren't. I have both hammar and ordinary, for want of a better description, on the boats. Despite working in some rough conditions the only ones we have had go off accidentally in the UK were
(1) Left by friend in the back of his rib when his team winched out the boat out and the water ran to the back...pillock!
(2) client who was told not to go paddling about wearing it and promptly did! !*^"!*
Out on the water we never had a prob til Paul Lemmer and i did a boat test for Rib Int off Holland in two ten metre TP Marine ribs. Force 10, gusting 11 my supplied by TP lifejacket exploded into life before we got out of the outer harbour arms. One helluva shock when they go off! Looking at the sea conditions and the amount of water being thrown about I decided to carry on with the jacket inflated and just hope I wasnt underneath the boat if it rolled. Good boats though!

Once one has gone off, manual or auto inflate what's the procedure for changing the gas bottle? I had an auto go off the other day. Got new bottles and its obvious that they screw in, BUT, screwed the bottle in until tight and it went off, (really cold on the hands ).

I've taken it apart and can see the pin that pops the bottle, and how the the toggle lifts to pop the bottle if you pull it

So is it just screw down until you feel pressure or am I missing something?

You need to make sure that the pin (that punctures the CO2 canister) has retracted properly. On the non-hammar auto jackets, the auto cartridge is sprung loaded and will push the pin up, and the manual firing toggle pulls a lever which also pushes the pin up.

If you've fired it manually (or if a new green plastic retaining clip thing came with the refill kit) then you can operate the handle and see the pin move in and out.

When you re-arm, take off the CO2 cartridge and the auto-fire unit. Check the pin has retracted, and that the o-ring seal is OK where the CO2 cartridge screws in. Replace the green plastic retaining clip on the manual lever (if required) - and then fit the auto-fire unit. BEFORE you fit the CO2 cartridge , double check that the pin is still down (I've had a couple of dodgy auto units) - and then fit the CO2 cartridge. The CO2 cartridge should be tight (by hand) against the o-ring seal.

Then get into a proper fight repacking the b*****d into it's outer cover......
