It can be done... rigging can be replaced with galvanised wire and mechanical fasteners when needed.. sails repaired by yourself, carry sailcloth, needles, waxed thread and palm, glass fibre, epoxy
and polyester filler, wood plugs and some 12inch squares of ply for emergency repairs
... some epoxy
that cures underwater is also a must. Good set of hand tools, drill, saws etc..
Fresh greens/fruit are essential to keep healthy, grow bean sprouts in a bucket of water(use rainwater gathered in catcher), buy green banana's they ripen as you go, carry semi dried fruits and canned..
gets tedious so supplement now and then with soya mince with beef stock cubes.. makes a great chilli. Onions are great they last ages and are crammed full of vitamins, garlic is another long life and good for blood... for your rice boil with some turmeric 1/4 tspn.. another source of anti toxins and great for sorting out boil and sores.. just clean the area, sprinkle on and cover with band aid, dries it out and aids the healing. Chillies are strong in antibiotics so use the dried ones when fresh run out in your cooking
.. adds a nice kick. Green bananas sliced into thin rounds and fried are delish snack food
, Coriander grows easy and fast, tastes great so a small pot of earth is good to carry as well.
Alcohol is incredibly cheap
in many places so occasional indulgence is cool.. just stock up where cheap and refrain where expensive... also a good sterilizer..
Store clothes and spare bedding in strong re-sealable ziplock type bags.. two clean spare sleeping bags sealed away are a must, they stash into awkward spaces easier leaving space for the less pliant gear
... Drink tea at sea.. save your coffee for anchor
.. you need to keep the bowels going and coffee is a blocker..
your eggs to make em last and store in the bilge
.. or hard boil em and store in large plastic jars in vinegar..pickled eggs.... yummy. carry as much extra water
as you can in 2 litre plastic coke bottles or whatever you get hold of.. that way if your tank pollutes you have a safe separate supply..
Phew... that's it for now... Over to the next guy...
