Here is a few of our dock we just finished up.
16'X16' with a 64"X16' walk way out. 12 barrels 55 gallon that were 23" diameter by 36"s. One under the walk way that is not shown in these pictures. Just have to add my anchor system to the front to level her out and a swim ladder.
She can hold a 2500# live load.
Cheers Don.
