RC, I just floated a new 8' x 12' dock with 30 gal plastic drums. Works just fine. (we also have a 10 ' x 10' dock floating on 55's, and i was hoping this one would ride a little lower on the water but it looks nearly the same.) started out with six 30gal drums under it, but that was a tad wobbly, so added two more. i noticed the 30gal drums are easier to manhandle and shove under the dock (than the 55's) when i added the two additional ones.
