If you have a recycle bin close by you can get plastic 1 gallon milk jugs
free.
Bleach bottles or any gallon jug will work but I understand that the
plastic in
milk jugs will last for decades.
Or check your local auto repair shop and pickup jugs from oil and
antifreeze.
These can pollute so milk jugs are better.
2 jugs filled with foam support almost 100 pounds.

is that how dolly parton stays up?



build a frame under your deck to hold the bottles fill the frame and then
cover
with galvanized fencing.
This will hold the bottles in place.
Once the dock is in the water the bottles tight against the bottom.

This will be cheap as hell and last for years.
