Mixed shoreline and mixed dock ages, so neighbouring properties often need different answers.
Exposure varies over short distances along this stretch, and dock ages vary just as much. The combination means general advice about the area is usually wrong for a given property.
The useful first question is how much open water the dock faces and roughly when it was built. Those two facts together predict the likely problem better than any amount of description of the symptom.
Exposure and build age together, since either alone predicts the wrong failure.
Repair work on the side of the lake that takes the weather rather than shelters from it.
Exposed water shortens cable life. That is the single most useful thing to know about lifts on this side.
The land side of the problem, and the one most likely to be treated as somebody else's job.
