I'm going to build a floating dock using barrels. I have 6 x 55 gallon plastic barrels that I can disperse equally around the platform edge. I have a small (1/3 acre) 10' deep protected pond - no big waves, wind, etc... Just want something to sit/lay/fish on, something the kids can use to swim from.

I know 8x10 or 10x10 would be more stable that 8x8, but I'm thinking the 8x8 size would fit my needs just fine and would be a little bit cheaper... Will I have any stability issues with a floating 8x8 dock? I'm thinking I should have plenty of flotation with 6 barrels, and could add water to each barrel to ballast and stabilize the whole system.

Thoughts on 8x8 floating platforms? Do I need to go any bigger than that? Opinions?

Thanks! smile
