I just re-read your original post and I think you should ignore most of what I wrote in my last two posts.
The reason is that for some reason I thought that you meant you were going long distances cruising, sailing to the coast of Africa or something, but now I don't know why I thought that! You actually said you were going to the islands to live aboard, well, in that case ... why not have roller furling ? Why not depend on wind vane self-steering ? If you're hopping from one civilized place to another and can pick your weather windows, etc, then I don't see any harm in it ...
I don't think I would worry that much about storm sails or getting stuck in places where you can't get parts if it is the Bahamas.
