I have a Sospender automatic one that I bought years ago for fishing. It's super comfortable and I've never had it deploy from getting wet. I could see how it could happen when kayaking though.
I didn't have time to read all of that, but I'd like to say that you two look smashing in those fancy bra's
Ok, so exactly what I described then Def
Weird that your inflatables need to be checked by a qualified professional. Here there are no such requirements, but if you are stopped and the officers check the date imprinted on the cylinder of your inflatable you could be in trouble. Still, the cylinders are usually good for (I think?) five years, and the date is pretty obvious on them. And, if you can replace a light bulb or screw the cap back on a drink bottle then you are qualified to change a cylinder.
If you want to cover postage you can have the Extrasport jacket.
