That is what I will do next time I replace mine, which hopefully will be the last time. Price ranges vary. Cheaper docks will not be as stable, more costly docks which I have been on are very heavy and can't really tell you are on a floating dock.
The dock shown below only has a few inches below the water line. The approach pivots on a large Pin at the shoreline. When the ice forms the dock simply pushes up and sits on top of the ice. very nice feature.
I have been on the one on the main webpage shown in the link. It's installed on my chain of lakes around the point from me. Will probably buy one of these next time when I'm ready...but they are expensive.
