      John, this is part of a series of articles on flotation, I wrote a while
      back on flotation and should be relevant to the Micro sinking, from what
      you have said, it look as if the Micro could use more flotation material to
      make it safe.

      If you want to see the rest go to "files" on flotation see; "Don's index"
      and click on the links. Don
