Slighty different take on this. Take a peek at this site.

It is written by a guy who has made multiple circumnavigations on a 28 foot sailboat. If you look on the left side, you will see a list of boat projects that he has done. One of them appears to be a nifty little kerosene stove. I'm not sure if that is the kind of thing you are looking for or not.

I've often thought about the parallels between preparedness and sailboats as I have an interest in sailing as well. If you look around enough, there are all kinds of sites that discuss food storage, rain water collection, simple recipes and other things associated with long term sailboat cruising. I think a lot of them could be used for long term preps as well.

Hope that helps.
