In 1989, I was part of a crew that took a 40'. special purpose multihull
, across the Pacific, powered exclusively by twin diesel
outboards. For much of the trip we used fuel
bladders. We walked on them, lived in the same space as them, then rolled them up when they were empty, to continue on the fixed tanks
. Once in Hawaii
, they could be unrolled, refilled, and continue on to the Phillipines, then onwards further.
They are strong, reliable, easy to plumb and disconnect. I will have a couple of 50 gallon bladders tucked away in my bilge
when I go cruising, in case I need to fill them for some extended stays in isolated areas. You can sell it for a tidy sum if you are in a remote
place, since commercial
fishermen really appreciate this hardware
. If you plan on carrying gasoline, be sure it's rated for it, and that you store the bladder in a secure location with excellent ventilation.
