Since you're going to be in the Caribbean and Bahamas, you don't really have to stock up on a lot of things, since you'll have access to fresh supplies on a fairly regular basis. That said, some things are far more affordable to stock up on here in the United States, than to buy as needed in the Caribbean. There are several excellent books on preparing for an extended Caribbean cruise, and if I get the chance, I'll post the one I was given by a friend. It's on the boat, and I'm not.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
