: I use these all the time for whitewater, rather than custom-fitted PVC
: float bags.

: 1) You have a a degree of redundancy - it takes four or five to fill each
: side of the boat behind the cockpit, so if one bag bursts you only lose
: 10% of your buoyancy rather than 50% if one of the PVC bags bursts (I use
: the 3 litre wine bags)
: 2) They do rupture catastrophically from time to time, but if you use a
: sligthly larger number of them, not fully inflated (a) there is less risk
: of failure and (b) you can just blow the remaining bags up a bit harder
: and be
: no worse off.
: 3) It's easy to add or remove bags as you vary the amount of kit you need to
: carry in the boat - put small things in the boat and blow a bag up to hold
: it in. All in all a lot more versatile than the normal
: one-big-bag-in-each-half
: arrangement.
: 4) As we generate lots more of these than I need (wine boxes are perfect for
: wine for cooking, even if you turn your nose up at drinking the stuff) and
: they store quite well flat, I always have several kicking around in the
: car in case I need a replacement - or want to lend a few to someone else
: who bursts a bag.
: 5) We've had several bought (and not cheap) PVC bags fail - usually in the
: cold as the pipe stiffens up and tears out of the bag.
: 6) They smell great as you let them down to fit more gear in ...

: All in all, even if PVC bags were free, I think I'd still use the wine bags.

Ok.
I surrender, not to the drinking part (I´s my wife´s job)but to the fact that wine cask bags is the thing.

another off topic question: how is your range of wine in wine cask bags? Is ther any good wins or just ordinary wines?
