Just a comment , a water skiers life jacket will not nescessarily keep you floatinmg face up. It will keep you floating but its not really designed to turn you over to get you facing up. A type 1 is supposed to turn you over face up. A type 2 may or may not (probably not) but its very unlikely a type 3 like the waterskiers use will turn you over. The big issue of course is mobility. the type 3 allows you to do the sport and will at least bring you to the surface. The best for sfaety , the type 1 is pretty bulky and awkward but it will keep you on top and will very likely turn you face up repeatedly even ofter you pass out.
OK, carry one!
