Video on effects of cold water / lifejackets

I found this interesting video on cold water incapacitation and why life jackets extend life expectancy. I did not know that in near freezing water, there is such a difference in your survival without a lifejacket (10 mins) and with (1 hour).

The implications are that, in cold water, any MOB is likely to result in retrieval of an incapacitated person. Safety gear needs to take that into account - you need a way of lifting a person aboard.

The Cold Water Boot Camp website is worth checking out.

Re: Video on effects of cold water / lifejackets

Jackdale - good info on Boot Camp website. So, it looks like obese people can survive much longer in cold water. Awsome, I think I will have another donut! Seriously, I wonder if closed cell foam lifejackets preserve body heat better that inflatables.

Re: Video on effects of cold water / lifejackets

Yes I think they do, I have a kayaking one that is particularly warm. But inflatables are so comfortable that I'm happy to wear mine all the time, even on hot days, while I wouldn't be happy to wear a closed cell. That's the big advantage of inflatables, they get worn.

I do agree that people do tend to wear inflatables, rather than the foamies. In Canada, if you are not wearing it, it does not count as a pfd.

Re: Video on effects of cold water / lifejackets

I was thinking, on my boat SOP would be foamies when water temp is below, say, 45 F, and inflatable above 45 F.

For me, float coat when air and water temps are both chill.
