To answer your question on the Cantilever desighn. When the breakwaters were built on the islands and main land areas years ago most people didnt have electricity. Also people didnt run circulators each winter to keep the ice from forming around the docks. So when the breakwaters were built they built in the Cantilever posts and built the docks over them so when the ice formed it had no direct contact with the docks. The tie off posting was installed so it was above the water line so that also could not be damaged by the ice. Now if you replace your posting and bring it down to the lake bottom and dont run a circulator the ice will tear if off the dock. Looking at the pictures its level and looks in pretty good shape. The Cantilever posting looks level and thats great since there part of the breakwater. If have any questions on how to maintain the dock you can have one of the local dock companys come out and tell you what you need to do.
