Love the design but do not want to leave the dock in the lake throughout the freezeup. I'm thinking along the lines of building two 16X8 sections then bolting them together once in the water. I would design the ajoining floor planks to flip up so to allow acess to the two sets of side supports. Put bolts with metal plates through the upper and lower sections, and voila, have a 16X16. Would also have to add planks to lock the billets in place for removal.
Can anyone think of any reason this setup would not perform as a standard one piece 16X16?
