I attempted to build a floating boathouse. With 50% of the project complete it took a much different turn. This project was built for completely free as all the barrels, wood, strapping, screws and lumber was free. Hope you enjoy!
I have built a dock and a couple rafts with 55 gallon plastic drums. I learned some things, the hard way. You want to seal the drums in the middle of your temperature difference. For MN sealing the drums at 30 degrees works good. The first dock sections I sealed the drums at warmer temperatures and in the winter they caved in some, so I drilled a small hole in one cap above the waterline, but somehow they still can fill with water. So seal in cooler temps. You can't have too much floatation. My first dock / raft had drums has 12sf per barrel, my last has near solid drums at 6.55sf per barrel. There is no such thing as too many drums.
Thank you for the reply to this video. I agree, the drums must be sealed at the right temperature or else there is a possibility for them to cave in the winter.
