Those plastic storage containers are likely to become brittle and
crack after very many months of being outside in the sun. Yhey're
not designed for such use. They same is true of the kayak if it
is plastic. (Fiberglass survives sun better) I store my kayaks in
the garage out of the sun. I've seen kayaks stored outside that
crack on any impact. And, I've got "plastic storage boxes" that
are falling apart from being outside.
there's 231 cubic inches per gallon of water and a gallon of water weighs
As someone else suggested, I would use two lengths of the lighter weight PVC
for yard drainage and a similar product with holes is used for foundation
They are only about $5 for 10' and the common pvc cements in the plumbing
make a reliable seal. Each 10' length would lift about 53 pounds.
If you want to get really high tech, rig up a valve system to flood the
tubes (to launch the
kayak) and a simple air pump to force the water out and lift the kayak out
of the water.
A commercial version of this is called a hydrahoist.
If my hubby heard this suggestion, he would require $200 worth of
electronics to operate the valves :o) I'm thinking about bevening one
end of the "rails" so the kayak slides on and a couple of rope handles
to push off. Looks good on paper :o)
