The main reason I'm rethinking this is that I'm contemplating more solo sailing.

How does the Coast Guard decide when to call off a search-and-rescue mission? - By Christopher Beam - Slate Magazine
To determine someone's odds of survival, the Coast Guard uses software developed by the Canadian Defense Department called the Cold Exposure Survivability Model. Plug in various factors—water temperature, air temperature, the person's height and weight, garments worn, time of disappearance, access to flotation devices—and the program tells you how long the person is likely to stay alive. In general, someone floating in 50 degree water can only survive four hours (PDF). In 65 degree water, which was the temperature off the Florida coast this week, it takes the average person as many as seven hours to lose consciousness. If the water temperature is above 70 degrees, he could survive for days—that is, if he doesn't die of thirst or exposure first. (The CESM can also calculate the odds of survival if someone is lost on land in cold weather.)

It seems to me the only completely failsafe PFD is the one that keeps you on board!

But as someone said fixed flotation can not deflate. So I wonder if the Spinlock would remain buoyant for three days until I either was rescued or died of thirst.[/QUOTE]
I dont know where you sail but where I am you would be lucky to last 3 hrs after that it would be irrelevant how long the life jacket stayed inflated.

My understanding is that it's normal to have to top-off inflatable vests once in a while using the manual inflation tube if you're in the water for quite a long time.
The other down-side I've read about inflatables is that they are so bouyant, it can be harder to swim in them than a non-inflatable. But you shouldn't be doing too much swimming while you're waiting for someone to home in on your EPIRB signal (you did leave the boat with one of those, right?). Swimming accelerates heat loss leaving you more voulnerable to the second biggest cause of marine deaths - hypothermia.
For us paranoid types, the other thing I really like about the Spinlock vest is the built in harness without those really heavy D-rings. Add the harness strap - and you've reduced another really big risk factor - you're more likely to stay on the boat in the first place!
Jeesh, its exhausting being paranoid .

So what is more likely, being unconscious or the mechanism not working? I suspect being unconscious is more likely as everyone has said the mechanism is well tested for a long time.

Without a life jacket even the best of swimmers will be exhausted in minutes.
If someone does not wear a life jacket that's their choice of course.
But if they try to tell me that the "REASON" is that they know how to swim I immediately knee them in the groin, to simulate hitting a life line, then through them overboard. As they suck in saltwater I calmly ask them to demonstrate their vaunted swimming skills unless they would rather grab the dock line I through their way.
A nice dip at anchorage on a sunny day fine but to unexpectedly find oneself in the water even in good conditions is something entirely different.
COAST GUARD AUXILIARY CONCERNED OVER RISE IN BOATING FATALITIES
Leading Cause: 90% of drowning fatalities in 2006 - victims were not wearing a life jacket
LOS ANGELES, Calif. - The Coast Guard Auxiliary is once again expressing great concern at the increase in the number of boating fatalities and injuries, and plans to step up its efforts to remind boaters that "You're In Command - Boat responsibly."
Published reports by U.S. Coast Guard Office of Auxiliary and Boating Safety, show that for the second consecutive year; the number of boating fatalities increased (710 deaths in 2006 vs. 697 in 2005) as did the number of injuries (3,474 injuries in 2006 vs. 3,451 in 2005). The reports also show some other consistent and disturbing facts; two-thirds of all fatal boating accident victims drowned. Of those, 90 percent were not wearing their life jackets.

As I'm also a little paranoid, when I test my auto-infatable vest next time, I'll also test using its manual inflation tube. If the auto-inflate mechanism fails (rare if the pill is not expired), next I'd try its manual inflation pull cord, and if that still didn't work, it'd blow it up using the manual inflation tube.
I think you eliminate the most risk by going with which ever PFD you'd actaully wear, whatever your preferences are. I've read in many places that most marine deaths by far are due to no PFD at all.
The new Spinlock auto-inflatable Deckvests seem to be enginered to take into account a broad range of the previously mentioned concerns (although no one product will address every worst case scenario), but they're not cheap. They are very strong, light weight, and have lots of features. Some might prefer a simpler approach though.
