Similar frame of mind Bob. Well you have a good boat for it. She will take a bit more weight than many.
I am going to look at this in more detail, as the subject has a tad more urgency to it these days. First off, need to establish just what a years supply of food actually looks like. Interesting exercise.
I seriously think of it as a good investment right now. Just as an example, a cheap tin of beans cost me 11p a year ago, is now selling here at 29p. Have food costs gone up in Texas?
If I invested a $1 in a bank, i'd earn a cent (1%). Four tins of beans would give me a net return of 100% by the same standard! And, I could eat em.
I'm not saying that the solution to the world banking crisis should be to invest in beans, but you get my point?
On the stowage issue, I have just acquired a number of collapsable plastic boxes, that stack, and can go across the floor and unused bunks in some of the cabins, and all lock together and be walked upon. Makes the headroom a bit tight though. But essentiality rules.
I think it was the Robinson family that managed to last 148 days in a liferaft in the Pacific once. I read their book long ago. Maybe I need to read it again.
The issue that will effect re-supply, will be a general breakdown of Law and Order. This is the African problem, where you can't run a farm, as people just thieve your crops, so you don't bother planting any new ones, and so on and so on. This is a very worst case scenario however. Very unlikely in the US I imagine, but civil unrest left to run riot could make it a local phenominon in certain areas.
My view of it is, that we just need to be able to "keep out of the way" for a bit, as historically, total collapse has been very rare, and very short lasting in any developed Country. Zimbabwe is perhaps the best example of a worst case, but we are starting from a different place anyway. The 1930s depression in US and Europe did not cause such a collapse. Yes, there were pockets of serious Sh** but with the ability to move about a bit, and our ability to pick up on radio broadcasts and cruising grapevine, we should be pretty comfortable let alone surviveable in a boat. And that is worst case thinking.
As some famous bloke once said.. Prepare for the worst, and live the best.
And hey, it's quite fun and an an interesting thing to do anyway. Stops us getting bored.
