Try looking at how to store fruit and veggies , dry em , jar em and such
we allways had a tripple tier fruit basket hanging in our galley . You may want to look at macrobiotic diets and high energy food and their values.
After some research turns out that apricots are super high energy source so we kept a bag of dryed on hand for our midnight watch junk style munchies, rather than hackin away at a bag of tater chips , that does nothing but put you to sleep .
A little investigation into what works and what doesnt may take up some time but thats half the fun . Just bear in mind that the reason Limeys are called so, is because of their discoveries of disease prevention during the golden era of sail . IE chomping into a lime or any type of citrus for that matter prevented scurvy .
Yarrr scurvey dawg .
Its hard trying to nap with that bilge pump alarm going off all the time
