I am in the process of shopping for a dock at my lakefront property. I got rid of a very heavy wooden dock that needed to be assembled and disassembled seasonally. I'm now looking for a floating dock that extends 40 feet to where the water is deep. One problem is the water depth is no more than 11 inches for the first 20 feet, so floating sections will sit on the bottom. Putting posts in for the first 20 feet runs the risk of getting mangled by the free ice that forms and moves in late winter. I'm thinking that I can get away with putting these posts in since they will only stick up about 12 inches, which would be a small bending force on the posts. The lake is 110 acres large. I'm hoping someone with experience can chime in.
