ABSTRACT:
A combination boat lift apparatus and piling securable to the bottom of a body of water. The boat lift apparatus includes an elongated upright outer tubular member preferably of p.v.c. tubing which has its lower end portion secured into the bottom and filled with concrete or like curable strengthening material. A drive motor is operably mounted within an upper portion near an upper end of the outer tubular member operably connected to a moveable plate mounted for slidable translation within the upper portion. An elongated longitudinally extending slot is formed through a wall of the outer tubular member for receiving a connecting portion of a boat support which is dependently connected to the moveable plate. An inner tubular member may also be provided and is preferred for added strength. The entire arrangement provides a long-lived piling structure which protectively houses the drive equipment for boat lift and support.
