I want to build two docks, one permanent and a floating one. The floating

The permanent one will be built of 55 gallon drums filled with dirt. Any
issues to look out for?


Might you consider using 55 gal drums instead of 15 gallon drums, and
part fill the big drums with 10 gallons of dirt of specific gravity 4
( = 4 times as dense as water...)

That would put the CofG lower than the 15 gal drums.....
