Thread: Hanging structure from floating dock?

Our floating dock is near the mouth of a cove on a very busy lake. The dock catches a good amount of wake from the large vessels that frequent the main channel. We would like to suspend structure from the dock, but I am curious if the bouncing structure would hold any fish?

So my thought would be to somehow anchor the structure to the bottom, use rope/chain and pvc pipe to build the brush, and a float just below the dock floats to keep the structure upright in the water column, and then rope/chain to the dock so it can be retrievable.

Is this a bad idea?

If placed under water a few feet it should work with heavy weight on bottom to hold down . We don't have docks most lakes I fish . But thinking about hanging some on bluff banks on a river drop . Think about brush piles in most shallower lakes with lots of boat traffic . The wakes have to shake the brush but fish still hold on them .
