It still dismays me to see our expensive breakwater falling apart when just a little bolt tightening would have prevented this. I am told that the shoreguard used is indeed about 20 feet long and that was not the cause of the failure. There is no way to repair this in house. I would not repair it until a study shows why the channel has filled in so badly. Then a comprehensive plan can be implemented to repair the breakwater and address the channel problem at the same time.
