A boat docking system having supports, a boat lift and a roof, the roof covering the dock. A fixed cover disposed over the boat dock and beneath the roof, the fixed cover attached to the supports by support brackets. The fixed cover includes a tarp having a roof and walls defining a covered space into which the boat lift can raise the boat. The fixed cover reduces the need for hard to handle traditional boat covers that attach directly to the boat to keep dust, dirt and insects out of the boat during a period of storage.
