ABSTRACT:
A foldable ladder for use with a swim platform of a boat is disclosed. A hinged panel adapted to fit in an opening in the swim platform pivots between a closed position and an open position. An upper ladder portion, which includes handrails, is fixed to the underside of the panel and pivots with the panel. A lower ladder portion, which includes a rung, is pivotally connected to the upper ladder portion. A control link is pivotally connected at one end to the boat and at the other end to the lower ladder portion. Raising the panel automatically deploys the ladder and closing the panel automatically stows the ladder beneath the panel.
