The clip is indeed well intentioned and somewhat educational as regards the effects of cold water - but not an especially good info clip for kayakers. But to be fair, it was not positioned as such. A savvy kayaker has many more options in clothing and skills than 9 people wearing sweats plunged into icy water.

The Coast Guard definition of any water temperature under 50 degrees is "arctic".

It is unfortunate that the Coast Guard recently announced that the term 'PFD' will be replaced by 'life jacket'. After years of use of the former by the paddling community the switch will generate some confusion.

There are a lot of nonswimmers who go paddling and put an unrealistic amount of trust in their PFDs when in fact a Type III PFD will not even have enough buoyancy to float them face up. The term "life jacket" is but more false reassurance.

Or, they will buy a stiff, bulky traditional "life jacket" (patterned after the old horse collars) and look bewildered when it rides up or comes off in rescue situations.

Neither bodes well for inexperienced paddlers in northern waters come the spring, aka 'the killing season'..
