The finger piers create a lot of turbulence but tend not to cause eddies of any real size so the technique will still work but not as well as in open water. If you have something solid like a bulkhead, it will create a large eddy and this will not work. Your boat will be affected differently depending on its draft(floats only disturb the water's surface).
When used correctly, a steady current can sometimes allow you to maneuver your boat more easily.
