A couple years back, National Safe Boating council attended the ACA annual
meeting. They came to promote the use of inflatable PFDs by kayakers. Just
pull the rip cord that activates the air cylinder and the tubes inflate. The
pull cord is at waist level. There you are upside down in cold water, extra
tight hot shot spray skirt holding tight to the knife edge glass cockpit
rim, paddle in your hand. What do ya do? 

 

Fish around for the pull cord, drop the paddle and pull the spray skirt,
gasp in horror etc.?

 

I took a USCGAUX basic boating course for power boaters over the past month.
They showed us an inflatable pfd that fills as soon as it gets wet. A few
days ago, a young USCG cadet was participating in a practice mission, feel
off a ship's ladder into the water. He was carrying about 60 pounds of gear
at the time. Hit the water and disappeared. It seems that the water
activated pfd that he had didn't have a gas canister hooked up in it. They
recovered his body after a while.

 

I want my pfd to be effective without possibility of failure.

 

I look forward to comments anyone may have about the value of inflatable
pfds. I will grant that just as victims are frequently so close to shore
that only a pfd is necessary for cold water boaters and that most of the
time for the first year or two the owners will be appropriately attentive to
inflatable pfd maintenance. I have noticed that a compressed air horn will
always work until the day it must work, at which point it ran out of air
last time out.

 

Concept of "foolproof" or "fail safe" sticks in my mind.

Obviously maintenance is required. A PFD isn't a PFD if it is an inflatable with no inherent buoyancy - its just a cordura-clad uninflated air chamber. However, combined with some of the inherent buoyancy with a wet suit, it can be a nice option for someone wanting unrestricted freedom of movement. I have two. hey are legitimate options, used cautiously. As I mostly solo I went back to regular PFD, the kind that floats. I did like the inflatable when uninflated for swimming - din't slow you dow. I did use the inflatable one day after surgery and I couldn't roll and got dizzy and swam to shore. After awhile, it got too difficult keeping my head up high while swimming the kayak behind me. The 30 plus pounds of buoyancy was great, but harder to swim in. Everything is a compromise, but you know that. 
 
I'm sorry about the fellow who died in service. Not exactly a nice outcome to a fall overboard.

to keep me up (and yes, I've tested that). It can be inflated by mouth so
you can choose to inflate it a little or more depending. Fully inflated it's
bulky but significantly helps the roll. Deflated it's not bulky at all and
you can swim in it pretty easily I think.

As far as a PFD being the best survival tactic in cold water... then what's
second best? A PFD and a drysuit? A PFD and a wetsuit? That seems ludicrous
to me. The logical answer is that the single best survival tactic in cold
water is a drysuit with suitable layers underneath and a PFD. A PFD alone
has to be somewhere down the list since quite a few people die with a PFD
on in cold water. And not many people die at all in cold water with a
drysuit and PFD on.

At the risk of thrashing this to death, I see it as an example of the 80:20
rule.

We all know that the highway death toll would drop if we could just get
everyone to equip their vehicles with a NASCAR cage, 6-way belts, a halon
fire system and then ease them into a full-face helmet. It's undeniably a
better tactic than relying on air-bags - but there would be some buyer
resistance.

Surely the choice for the USCG is between one simple message - "spend $ 50
on a pfd and wear it" (in your kayak, your small fishing boat or small
sailboat) or an obviously better message saying "spend $ 800 on a drysuit &
pfd and wear them"...

Or, more truthfully but also more demotivatingly: "please spend the $50 -
but maybe don't bother, because it's not a perfect solution".

It looks to me that USCG has maybe 5-10,000 people a year fall into cool or
cold water - of whom about 500 don't climb out. They are looking for a
simplistic 'bang-for-buck' message and they believe they have found it. If
they could knock that 500 in half - or even just back to 400, they'd be
happy.

Whatever the USCG front men are saying, I think that the organisation has
decided that the result of pushing for a 'perfect solution' will be less
effective than pushing for an affordable one which has some chance of
widespread adoption.

What about a ordinary pfd for paddling and an inflatable as backup?

Some years back at the beginning of my paddling career I didn't possess
the gear and equipment that I now find natural.

So early in the season when the water temperature was about 45 F, 7 C, I
went out with a trip leader but was caught by a change in the weather.

I had not been too convinced about my own capabilities, so just the week
before I had bought an inflatable and adjusted it to fit over my pfd,
and stored it in a tubing next to the seat in my kayak. The salt tablet
was replaced by a small nut to prevent accidental activation.

On our way back I capsized in the lively sea and couldn't get back in
the kayak. I pulled the inflatable out of the kayak and "dressed" in the
water. After dressing I activated the pfd-cartridge. Then I hanged on to
the stern of another kayak and was carried with my legs out of the cold
up on the deck of the kayak and supported efficiently by the buoyancy
and the hood of the inflatable. It gave a good protection against the
cold waves. More than half an hour later and with my legs pretty blue we
reached the beach. On our way towards the beach my rescuer capsized
twice in the breaking waves and I had to turn him back up. I shall
always remember the experience.

Now I use the pfd as a body harness and I don't know where I should have
my gear if it wasn't there. My skills are much better and the inflatable
is no longer in use. Today I prefer my dry suit as precaution together
with my body harness, vhf and plb. Then I didn't know better, but the
inflatable proved its worth. It was a strange feeling to go back to the
store and ask for a new co2 cartridge.

So, what about a ordinary pfd for paddling and an inflatable as backup?

best regards

No real argument with that line of thought - as long as you always wear your
non-inflatable PFD - and don't leave it off because it's too hot or too
bulky.

In NZ, most kayakers (except for very casual sit-on-top users) are fanatic
about wearing PFDs - which I think is great, but surprising, as we are not
generally a very safety-conscious nation. 

However, there are many other places where I have seen lots of PFDs under
deck bungies... I reckon that an inflatable PFD being worn is better than a
non-inflatable PFD on the afterdeck.

The inflatable PFDs are widely used by local sailors (especially dinghy
sailors - lasers & the like), but I know less than a handful of kayakers
using them. That said, those few include some of the most blue-water,
long-distance guys I know.

I have thought seriously of using an inflatable in conjunction with a
drysuit - as the drysuit gives me so much (immediate) floatation anyway. It
would be easier to travel with an inflatable PFD (much less bulky). I did
check for our Alaska trip and was surprised to find that airlines
specifically allow a CO2 cartridge on the PFD and one spare (YMMV).
	
Now, in defence of inflatable PFDs, they all seem to have an oral-inflation
tube in case the CO2 fails to work. Note that this is supposed to work even
if the CO2 canister is missing. Not ideal - but better than nothing.

One thing that appeals to me about the inflatable PFDs is the much greater
head support (or face-out-of-the-water floatation) than is found in any
non-inflatable PFD I've ever seen. Perhaps of no value in the short term, as
our maximum chance of unconsciousness will be at time of immersion - and I
don't think I want an automatically inflating PFD... so perhaps this is not
of much advantage until you've been in the water long enough to start losing
consciousness.

I do also agree that long term CO2 maintenance is a worry - all those with
out-dated flares, raise a hand ;-)

Just my 2 cents...

that is a very interesting story .....and to be honest i doubt it happened  
the way you have presented it,
it sounds a lot like the "stories" about WMD's .......
would you please send more details i.e. when/where.... i think i'll google  
it just to verify .....
thanks,
steve
