Couple other suggestions - if any of your electronics get wet and it's not salt water, take out the batteries without turning it on (turning it on can short the electronics) and let it dry out - toaster oven on low heat, dessication chamber if you work in a lab, or front dashboard of your car on a sunny day.

If it's salt water, you probably don't have a chance of saving it.


And another reason to keep your cell phone in a bag on your front deck - you can use it if you need to call for help. I can still use my cell phone in the drypak bags and it's strapped to my deck (arguably, you can strap it to the pfd or keep it in your pfd pocket)... if you've got your cell phone stashed in a drybag or a deckbag with a bunch of other stuff and you're out of the boat or there's some emergency, you don't have a waterproof way of getting it out and using it.

VHF radios are great (for those - remember that they need to be tethered, because a lot of them do not float and will sink like a log even if they're waterproof) - but they work via line of sight. if you're in the water or just barely above the water, you're possibly not high enough up to get a signal without having an extendable antenna for it. In a lot of places, cell phones are a better bet for getting help.

As for signal flares, I've seen a couple flare demonstrations where people grab the flares they've been carrying around in their kayaks for just in case and then start trying to shoot them off... usually roughly about 20% of those actually work because of the age, water damage, whatever... stashing those flares individually in condoms seems to be very effective at keeping them working though.
