Bill, I've been using what we call in our family "frozy water"
bottles for years.  It works very well.  Another sailor I know 
uses frozen vegetables as well.

As to insulation - you can make insulated enclosures for the
commercially available iceboxes quite easily.  The trick is in
controlling the condensation.  You don't want it to form inside 
the insulation, so closed cell polyurethane is a good material.

A polished aluminum or stainless skin would provide both 
structural strength and reflection of radiant energy.  I would
expect that a couple of such could provide cold storage for 
several days, assuming that the second one was not opened the 
first two days.

As few of us are going to spend more than a week away from a 
source of ice, this approach might work pretty well.
