Ed, the pics are on the way. Just cry uncle when you've had enough. I used 6 barrels per 8'x16' section of dock.Iused 2 barrels on the walkway with one end being on shore. I made the walkway 1/2 the size of the larger peices so it would float at the same level as the rest. We have had 9 people on it at once, and it didn't lower into the water much at all.
