When I was making passages we had no fridges or freezers, so I can't speak to that. But as far as planning food (we didn't "ration" except for treats of course so they wouldn't all be gone the first week

), we basically brought as much as we could fit. This included canned goods (fruit, veg, beans.... anything you might actually eat), dried beans and the like, plus things you could use to make fresh food out of non-fresh food (so baking supplies, yeast, flour, etc.)
Nuts, eggs (not refrigerated - we just turned over each dozen every few days), peanut butter, olives, sardines, etc.
Then some treats: Cookies, crisps, chocolate, candy. Jello, pudding (if you would eat them).
Fresh stuff for as long as we could keep it: Cabbage, potatoes, onions, apples, oranges, limes, etc.
Condiments and special stuff: Horseradish, olive paste, pickles, dried tomatoes, hot sesame oil, vinegar, oil, peppercorns, salt, you get the idea.
Coffee, tea, hot chocolate, etc.
Also: Tuck away some food/treat/surprises. They take on a value all out of proportion to what they normally have ashore on, say, day 22.
Paper towels and toilet paper (cases).
I know many people say "Don't worry about it; people eat the world over!" And that's true of course. But we figured well, we have a car and shops we know now -- it's never going to be easier. Never regretted stocking up as much as possible in advance.
I guess with a 57-footer maybe "take everything you can fit" would be too much (?). We never had that problem (32'). I can't imagine you'd need to ration (unless maybe you have a large crew).
