I used my 19 yr old grandson to help me build a 12x16 floating dock. I used 55 gal drums for floating the pier. I set it up where I attach a hand control trolling motor to move the pier around the pond when needed. And it works like a working barge or platform when placing or adding structure around the pond. And it can be moved to the center of the pond for a place for the teenagers to swim or sunbath off of. U can't do any of the above with a fixed pier. And it is pretty stable, not perfect but I have little to no skills when trying to be a builder or mechanic. So all in all I'm good. I am thinking about building a floating walkway to extend the pier past the 16' of pier I have now.
