some good ideas--just so you don't have to run thru the
    entire post again i'll put a few comments here..    

   this is the sort of big wilderness lake i would be up against.
  in this photo i was crossing the inside of that large bay in
  rough but stable water when i saw a very heavy wind comming
  from the north..you can see the whitecaps out in the blue 
  water..i made for shore and was pulling the gear out when the
  wind hit..my canoe is very satble and made to travel thru this
  sort of country but i'm not a trapper heading for his cabin
  with a load of fur..i'm on vacation so solid ground is better
  than a wind whipped lake..
   looking back at this photo i thought what a joke the flasher
    on the PFD was..who would be around to see it and how would
   it show up if i was out in the middle of that lake..
   if i could swim off a lake like this and get ashore with
   enought energy to get a fire going and make a shelter the 
   plan was to hang the flasher by the shore to attract attention.   
    OK..about your good comments...a knife--i carry one on my
     belt most of the time..a Mora 2000..it's a good size sheath
       knife that would handle most chores..in warm weather when
      it's shorts and a tee shirt i keep a SAK in a zippered
       pocket..
     the compressed soup only comes in pea as far as i know.
    pea soup with bacon fat in it is very high in food value
     which is why is was used as a iron ration..
    water bag--i will add one to the kit..having water in camp
    will be handy..the lake water is about as pure as it gets
    and as i drink it all the time--for many years--i don't
     need treatment tabs..  
    the duct tape is the small rolls you can now get in a 3 pack
     at REI..it seems to hold up well but i'll swap it out and
       take fresh rolls and keep the used for odd jobs at home.
     heatsheet??--they seem too bulky for a PFD pocket..i have 
      not seen one in real life but i'll check it out..the mylar
       blanket is to be used as a roof for a shelter and the
      bag as something to try and keep warm and dry in..
     lifeboat matches have a shelf life???..i'll swap those
       out too..what i would like to find is a lighter--not
      a Bic--that with one press you can get a large strong
      flame that keeps going without holding the starter down..
      a old Zippo fills the bill and i see butaine lighters
      that might work..i have read accounts when people are
      so cold and shakeing that striking a match or holding
       a lighter is just about impossible..and i don't want
      sparks--if there was a one shot--pull the tab and drop
        in a pile of wood fire starter i would like to find it.
      i have a whistle on the PFD--i would spent a lot of time
      blowing on it..i have been in places where i have not seen
       anyone for days and then around a point comes a couple
      canoe loads of fisherman or another solo tripper out
      on his adventure..the park service also makes fly overs
      but they are not looking for lost campers but watching
       for fires and are kind of high up...
        but the chances are small that i might have to use
        that PFD --falling down on the portage and busting
       a hip is far more likely--thats another story--
