I thought boat owners might appreciate this posting of my shore docker. The docker is made up of 2×6 spruce (cedar would be better). The casters are rubber and 200 lb. rated. So far they seem to be working ok. The docker saves me from launching at the boat ramp down the road. Why not just build a dock you ask? The reason is that the prevailing winds bring in some pretty strong waves and a dock just would not do. So for those who have a similar situation, this might be a solution for you. bye for now!
