You know the new $125,000 Cattle Landing town dock, about one to two years old, is a floating concrete dock, and supposedly according to its manufactorer's website, using an ice-eater/water circulator is not really needed to protect it from the relatively thin ice present at that location, so maybe you could bring this to the attention of the Meredith D.P.W., and they would not need to be using the ice-eater there.
