Quieter water and steeper ground, which moves the problem from the dock to the way you reach it.
Less traffic and more shelter means hardware here generally lasts well. What is harder is the approach: where the bank drops away steeply, the gangway is spanning more vertical distance, and every foot the lake moves changes that geometry more sharply than it would on a gentle slope.
The practical result is that gangway hardware does more work here than almost anywhere else on this shoreline. Hinges, rollers and slides see the full range of lake movement translated through a steeper angle.
When a dock in this area develops framing problems, it is worth checking whether a binding gangway has been pushing on it.
Gangway hinges and rollers, which work harder where the bank is steep.
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.
Flotation fails quietly and then all at once. The warning sign is geometry, not sound.
