Most marinas have a supermarket nearby, so you can do your shopping on the day you board. Buy enough for the first few days, plenty of water, and food that is easy to prepare in a small galley.
If you run out during the trip, you can stock up again in the next marina or town. Shops on remote islands and in the marinas themselves tend to be expensive, so buy the basics before you head somewhere remote.
