Pintos and Red beans are a lot tastier than black beans. The amino acid profile of corn complements that of beans much better than that of rice does. But here's the thing... beans, flour, dried pasta, rice, etc is subject to weevil infestation when kept on a boat for more than a couple of months. Is eating weevils a problem for you? If so, I would not rely too heavily on these foods alone. Make sure there is enough canned stuff to survive on. One good thing about canned food is you can eat it right out of the can if your stove goes south on you or you run out of fuel
. Same for MREs if you happen to find a cheap
source. They store pretty well, too.
In most tropical or temperate waters, it is fairly easy to catch an occasional fish with a trolling line. Not something to absolutely depend on, but it sure helps to stretch things and vary your diet. Make sure line and hook are waaaaay stronger than you would use sport fishing! A bicycle tire makes a pretty good snubber or shock absorber for a trolling line.
Ever ended up with a couple dozen mystery cans, the labels having fallen off? It sucks to try to make a meal out of whatever is in the can you picked to open. Mark the tops of the cans!
Personally I think it is a bad idea to try to stock up with enough stuff to last an entire multi-month voyage. Have an emergency
stash of long-lived, easily stored stuff, a good supply of hard to get overseas stuff, and from there, just stock what you will need for about twice the duration of the upcoming leg of the voyage, and re-stock along the way. Weevils. Can damage. Glass breakage. Moisture. Ants/cockroaches. Plenty of reasons to not depend on a simple one-time bon voyage trip to the supermarket to feed you until you get home again. Oh, and weight/space issues. Three or four months of provisions for just me alone would be more than I could store on my little boat!
Don't forget that dried provisions require cooking water
. Canned stuff already has plenty. So if you go big on dried stuff, make sure your freshwater storage
and/or making capacity is up to the extra demand.
