That's part of the experience though, isn't it? What's the point of going to some far away location and seeking out a McDonald's?
You had to use McDonald's as an example? A good friend whom I otherwise deeply admire would perish without McDonald's. Partly because he's a picky eater, partly because he's scared of food poisoning (in all candor, few Americans are as willing to explore street food as we are).
Thar said, someday we'll make it to the Bahamas. Having been there, I wasn't impressed with the restaurant scene and the grocery store (the one in Georgetown) didn't have a great selection - all came by ship one day a week from the US. Pre-provisioning makes sense there. If I were doing The Loop, Id provision some special stuff (Biscoff cookies in bulk from Costco) but wouldn't go overboard on regular provisions.
@Jklotz - I seem to recall you mentioned elsewhere you rode a BMW GS style bike down through South America. Unless you were in the Andes, you didn't have refrigeration not much space to store goods. Far cry from your NP45....
Topic here is controlling costs. Probably the number thing someone can do is to choose a smaller boat. At 36-ft, Weebles is welcomed anywhere. We obviously didn't buy her 30-years ago aiming to cruise long distances, but she's proven much less expensive to berth, repair, store, and repair (yes, I said that twice) then the 50-60 footers we've hanged with. She's small enough that we usually wash her ourselves whereas bigger boats are too big and cost several hundreds to have washed even in Mexico. Or you spend two days washing them or just let them gather salt and crud. Bottom cleaning is the same story.
Want to control costs? Get a smaller boat.
