Inflatable PFDs in the south: Manual or Automatic?
 
I am looking into "investing" in some inflatable PFDs for the First Mate and myself. I am leaning toward automatic for obvious boom-to-the-head reasons, but I have seen some concern about those in high humidity environments.

the triggering device is a compound that disolves when it gets wet, which lets the hammer down on the co2 cartridge. Ive not heard of humidity causing it to disolve

Hopefully this will be easier than the "fin vs. full keel" discussion.

Automatic - No issues with premature inflation even in rain.

That's good to know. I was ready to pull the trigger on a couple of West Marine automatic PFDs today, but one of the reviewers said that they found inflated PFDs when they pulled them from their lockers. The reviewer was from Louisiana, where Humidity calls home. We are one state to the north, where she vacations during the summer.

Could have been an older review?

Some good deals out there. I just paid $89 for auto inflate w/harness made by Revere (show price). Sailnet sells them at a competitive (non show) price. Quality seems good.

Premature Inflation
 
A little more info.

We did have one (out of 3) "pill" automatic inflatable WM premature inflate in our boat locker but after 5 years, but the the "shelf life" on these things is 2-4 years, depending on Vendor. The Hydrostatic ones are less likely to premature inflate.

I have a hydrostatic one that has been stored for a few years in MD and MO. No issues with premature inflation. Humidity in MO was over 80% relative for most of last summer.

Does it matter if the auto-inflate device is stored upright? Maybe condensation dripped in?

That is what I was wondering as well. Here is the link to the West Marine review. Third one down, written 3/17/2012.
