Provisioning recommendations I came across at lunch today.

We have learned to only take what you use. Extra stuff just takes up
space for things that you really need. I start by buying a ton of paper
towels and toilet paper. Almost everything comes out of our big hanging
locker and it becomes the paper product locker. We also purchase cases
of already cooked canned meats from a company called Werling and Sons in
Ohio. There are a number of other companies that folks use; we just have
always used Werling. The delivery is prompt, the product is good and the
cost is reasonable. I ordered 4 cases for our last cruise and had a lot
left over so only got 3 this time. We rarely are unable to find food. We
also take canned vegetables and fruit, enough to last about 6 weeks. If
we get to a place we really like, we don't want to have to leave for
lack of provisions. We stock our small Adler Barbour freezer with as
much frozen meat as we can. Take ground beef, etc. out of its original
packaging and place in freezer bags to maximize space, which allows you
to fit more in. Sea Trek also gets stocked with cereal, snacks, sodas,
and whatever other items you really like and are afraid you won't be
able to find outside of the country. Always eliminate extra cardboard
and packaging and try to store as much as you can in zipper storage bags
or airtight containers. You may want to try inserting a bay leave into
each baggie of food to deter bugs. (They tell me that bugs don't like
bay leaves, but who knows.)
Because we like particular hygiene products, I buy enough of those to
last us for the duration - razors, deodorant, shampoo, toothpaste and
those sorts of things. I also purchase enough vitamins, cotton swabs and
balls, stomach remedies and the like to last the entire length of our
trip. This action was spurned on by the cost of Pepto Bismol in the
Bahamas!! I also don't want to have to look for sensitive toothpaste in
a 3rd world country. We keep a storage list of where everything, and I
mean everything, is on the boat. If we forget where we put something, we
simply look it up in the computer or on the hard copy that we print out.
After you bury things deep in your bilge, you will be glad you took the
time to take inventory.
