Long-established lakefront, which means a lot of docks arriving at the same milestone together.
Where shoreline has been developed for a long time, a good number of docks are still running components from an earlier era. Flotation in particular tends to be the item that has quietly passed its service life while everything visible still looks sound.
That makes freeboard the most useful thing to watch here. A deck that rides lower than it did is reporting a flotation problem well before any board or bracket looks wrong.
Calls from this area skew toward floats and connections rather than mechanical failures, which is what an older dock population produces.
Original flotation quietly past its service life while everything visible still looks fine.
The wide water carries weather further. Damage here is more often wind-driven than debris-driven.
This end of the lake asks more of a dock than the narrows do, and the repairs reflect it.
Deeper water and bigger boats mean bigger lifts, and bigger lifts fail differently.
