ABSTRACT:
A second stage lift assembly for a moveable boat stern platform is disclosed and provides the ability to raise the moveable platform up an additional higher amount as compared to it's in-line level with the boat's walk-on deck or fixed platform. By being raised higher when the boat is moving, the moveable platform avoids dragging problems often encountered where the moveable platform remains at the same height as the walk-on deck or fixed platform.
