Depending on where you are going, stock up on items you like but maybe either; no there, or priced out of reach. Me I stock up on coffee, smokes,
beer, some wine( never met a box of wine I didn't like!), comfort foods and tp and pt! Like someone meentioned, palm fronds do not make good tp! Pull the rolls out of both and vacum pack them to save space. A food saver or the like is a godsend, you pay on the front end but save on the rear end
. Moutain House is a good back up if you have plenty of
water, I always buy cases of bottled
water to have on hand, store low in the
bilge, teas, instant hot coco, soups things like that help round out long watches. If you have a
freezer, then you have it made with meats and stuff you like that aren't
sold in places you visit. Can you really count on catch
fish everyday? and do you really want a fish only diet? Go to some of the prepper website/blogs for tips on long range food storeage, some good tips there that apply to cruisers as well. Just use you fav search
engine and type in preppers.
Good Luck!
