The automated, rotary retractable dock will have the elevated structural skeleton of a regular or seasonal dock. This includes the pilings and cross members. The pilings will support guide rails running (track-like) between them. The pilings will also be fixed with cross bars, and rollers which will partially support the material that will serve as the dock surface as it is extended or retracted. This dock surface "material" can be a wooden, metal, or plastic, interlocking grating which will be wound up at the land-ward end of the dock/bulkhead, into a housing unit. Wheels or rollers will be placed periodically along the side of the grated decking material. On one or both ends of the structure, an electric winch will pull the dock surface material out across the structure (water-ward) and on the other end, retract it (land-ward). The system will have both land-ward and water-ward "on/off" switches and a remote control.
